Question From David (1954):
El Nino has struck in Southern California, so naturally, the wiper motor on my daughter's 1954 Imperial has gone kaput. I got on the front seat of the car with my back on the floor and my legs over the seat.Whoa, really uncomfortable.But, I could read the motor number: EMG 4102.But, the one I have in the car may be fixable. But, how the heck do I get it out? There seems to be no room to get-at-it by going under the dash.Can I remove the front of the dash?I am not a seasoned mechanic, but I am fearless. I once started to take apart the dash, but I got stuck and made no progress on getting the front of the dash off.Are there any suggestions?
Reply from Jay:
I'm not familiar with the '54 Imp to offer any mechanical help, but I have a suggestion that will make the car usable in subsequent storms until you get the motor situation resolved. May I suggest treating the windshield with Rain-X? Rain-X is a glass treatment that seals the pores in glass surfaces. The surface tension of the water where it meets the glass is reduced and only VERY SMALL droplets are able to form on the glass before it runs off. Treat your windshield with this stuff and you will not need windshield wipers. (I'm not kidding!) Sitting at a traffic light or at highway speeds, the tiny spots of water are constantly moving and either run down the windshield while the Imp is stopped or get blown off anywhere above 40 mph. It's really amazing to see such small droplets of water move and dance around in the breeze where larger drops of water tend to glob onto an untreated windshield. I have treated all the windows and outside mirrors of our '66 Imperial and drive it in the rain regularly (although I wish I didn't have too).
I have run my '66 at speeds up to 80 mph in pouring down rain in very close proximity to trucks and other traffic (LOTS of spray) and never have I had to turn on the wipers. The Rain-X treated windshield clears itself. I'm sure that people that see me think that I'm crazy running in a hard downpour with no wipers, but what they don't know is that my visibility is better than theirs! Any major auto parts chain carries Rain-X. You shouldn't pay more than $4.50 for a bottle. I am about halfway through my first bottle and I have treated probably about 45 to 55 running feet of Imperial glass. It sure beats having a malfunctioning wiper arm or blade digging grooves into your Imperial windshield!
Follow-up from Chris:
I too have a bottle of Rain-X in the garage but that's where it stays now. I found that the car becomes addicted to it, and if I didn't reapply it (and every once and a while use alcohol to strip it off the windshield), it just smeared after a while when I did use the wipers. And then nothing would let me see clearly at night or after I use the washers. You'd be surprised how easy it is to drive in the rain without wipers on a "natural" windshield. I do it all the time in my Grand Cherokee (above 40 it runs right off) and my '87 Honda CRX, back when I'd drive that car in the rain (after 11 loyal years the CRX has earned the right be treated like the rest of my collectibles), and in fact most any car I've owned. (I discovered this on my first car while driving to high school and have always been kind of fascinated by it.)
Question from Joe (1956):
I need 12 wiper refills for my 56 Imperial. NAPA has them only as the blade assembly. I purchased 2 they are flat grey. I the wiper refill out and tried to use it in my existing Imperial blades but they do not match up. they do not have the squeeze connections. Does anyone know where I can find some?
If your '56 has two red [or maybe faded pink by now] tabs on each wiper assembly, as does my '55 DeSoto, it's an Anco unit. Check an Anco display and you should find a replacement.
Call Ficken Wiper Service in West Babylon, NY 631-587-3332. They've been in business since the beginning of time and have loads of obsolete wiper items. Ficken also does wiper motor rebuilding. I've always been satisfied with their work.
Question from Kerry (1957-59):
How the heck do you get the vent screen off on a 57-59. This is the screen directly in front of the windshield between the wipers. I'm stumped.
You'll have a lot of work to access the nuts which hold the grille.. The Imperial engineers had a very bad day when they planned this air intake grille. In fact the 58 grille was modified (even if it's the same grille when you look at it from the outside). To remove the '57 grille:
- Remove the fiber heater cover (engine side) + hoses + blower
- Remove the heater & the A/C evaporator if so equipped. (you've to remove the distributor cap and perhaps the distributor). But to remove the evaporator, you've to disconnect the damper door linkages from the inside ! !
- Now you've access to these stupid nuts which hold the grille. In '58 the nuts were replaced by studs with spring inserts.
Just pry out the center section and you'll find a screw. Remove it and the two screws on the portside ends of the grill and it comes right out.
Question from Greg (1961):
Windshield wipers on my '61 Imperial are now erratic. They operate a few seconds after you turn off the switch, and only work on full blast. We replaced the switch, but still have the problem.
Is this likely a short in the wiring? Or should I try having the motor rebuilt?
Reply from John:
It sounds like a ground problem. When I got my '60, the switch was loose in the dash they only worked full speed unless you moved the switch a certain way Tightening it properly cured the problem.
Question from John (1965):
I'm trying to get my headlight switch out to replace the breaker to solve my flashing headlight problem.
But to get the headlight switch out, I have to remove the bezel and to remove the bezel I have to remove the wiper switch knob.
I haven't been able to locate a push tab on the back of the wiper switch to release the knob like I did for the headlight switch. I can barely get a hand back there to feel around, much less do anything. So how much of my dash do I have to take apart to do this? Does the knob come off from the front?
I can't say for sure on a '65, but most Mopars have either a set screw in the knob, or they just pull off. The headlight switch is the only one that has the tab to remove the knob. If you cant find a set screw on it, try to just pull it off, should come off without a problem.
I went out to the Grey Ghost, to double check my thoughts and I was actually right for once! LOL! There is a slotted set screw on the knob itself.
Question from Randy (1965):
I have a problem with the windshield wipers on my '65 Crown. They sometimes do not park correctly, that is the tip of one of them will remain about 3 inches above the other when the wipers are turned off.Any ideas on the fix???
I have what seems to be the same problem on my '65 Crown. If you turn the wipers off when they reach the lowest point of travel, do they both stop evenly then? If you turn the switch off when they are not at the bottom oftheir travel do they park unevenly?
Remove the arm from its splined knob by pressing in on a tab underneath the wiper arm close to the windshield while lifting it straight off. Then, rotate the arm on the knob one or two splines until it lines up properly and snap it back on. This will work if your arms are not bent or any other problems exist.
Check that the motor is mounted tightly also check for any bent linkage. Not sure if this will do the job, but had a '61 Newport wagon with this problem that was the cure.
This appears to be one of those situations where they all do that. At least it's true of the 60-66 era Imperials. I've only known of 2 Imperials (both'64's) that always parked their wipers neatly at the windshield molding.Usually I can get mine to park properly by turning them off while the arms are in the downswing mode. But, if for any reason your wiper arms were ever removed from the posts they may have been re-installed a bit out of phase. Try removal, then re-install in the correct position. Note: give them a test run on a wet windshield to be sure they still sweep the glass properly.
Question from Joachim (1968):
Question regarding wipers on 1968 Crown Coupe
My car still has the original type wipers, that is the arm and blade are in one fixed assembly, therefore not separable, I only can replace the rubber, but the wiping of the rain remains poor. Can anybody tell me if there are newer types of arm/blade combinations available for this model, if YES please supply brand name and part numbers.
I am not sure that you cannot separate the refill (the rubber insert) and the blade (the metal part that holds the refill) and the arm (the piece that goes from the blade to the pivot on the car) into three separate pieces.
My '67 has its original wipers, and they used the airfoil design in '67 (which I think went away for '68). They are completely separable as described above, and they actually worked quite well the one time I got caught in a rainstorm (and it was on a freeway, so I got to test them at speed). If you truly cannot detach the blade from the arm, maybe if you find some 1967 wipers you'll be happier with them (yeah, I'm sure there are a lot of those lying around Australia, but maybe a search on the 'net would reveal some... they are the same for all C-bodies). 1967 and 1968 should interchange fine... and 1965-66 Chrysler, Plymouth and Dodge wipers would fit, but they are chrome in the those years, the antiglare matte silver finish being new for 1967.
The air foil wiper blades that Chrysler used as standard equipment back then was unique to Chrysler products and generally not supported in the replacement parts end of things. The blade assembly should disengage from the arm unit at the pivot point. Possibly some hidden tang to depress or something?
I have observed that the quality of replacement wiper blade inserts has seemed to deteriorate in the past decades. Nothing like back when Anco and Trico were their own companies. On your existing blades, make sure they are not kinked or slightly twisted such that when the new inserts are installed, everything lays in there smoothly and "straight" of wiping edge.
Stateside, there might be some NOS parts vendors that might have new blade assemblies to fit your vehicle. Some of the muscle car blades might fit too, but be not quite so long compared to the Imperial's blades.
Converting your existing wiper arm/blade unit might be an option, but it would take some careful measuring and eyeballing to make sure they would work correctly, park correctly, and not hit the left hand windshield pillar at full sweep. I suspect the mounting stub might be the same diameter for many years and also for non-Chrysler products, but finding a arm with the correct length and angularity would be the trick. All of the newer vehicles up here seem to be going to the shepard's hook style of arm, in black, and use wiper blade assemblies are very industrial in design, plus stick up pretty high too.
Question from Dave (1968):
Also, I understand that the original, metal, airfoil-style wiper arms used in 1967 and 1968 may still be available. My search of the NaPa and Anco catalogs hasn't turned up a useful part number. Anyone know the right numbers?
The wiper numbers are: arm w/o blade, wiper 2889958 blade w/refill 2889960 refill (only) wiper blade-2427671.
The wiper arm without wiper blade (according to the Mitchell Manual) is part #2889958.
Question from Roger (1974):
What is the plastic part that holds wiper arm on its in the fresh air intake area?
Reply from Rob:
Do you mean the bushings that hold the linkage on? They are little white plastic bushings. I bought the whole set from a Dodge dealer for a few bucks ($6?) a couple of years ago. You can just squeeze the parts on with a Channel Lock. The only real difficulty is that you have to do them in the right order.
Question from Tim (1975):
When I turn the wipers on, the one in front of the driver hits the A-pillar. How can I adjust it? They also don't park in the concealed position. They stay up where they're visible.
Reply from Elijah:
Two possibilities on this one.
1. Someone has taken the wiper arms off, and not put them back on in the
right position. This sounds most likely, since the one wiper is overextending. To correct this overextension, turn on the wipers -- as soon as they have extended all the way (and the driver's side one is bumping the pillar) turn off the ignition key to stop them in that position.Then remove the driver's side wiper arm (the arm will lift away from the car on a pivot at the bottom of the arm. Underneath this will be a small tab which will pull out. Wiggle and gently pull the arm, and it should come right off). Reposition the arm so that it is about an inch or so away from the A-pillar. Turn the ignition key back on, and let the wipers go back. Then turn off the wipers. I suspect that the one you've
adjusted will return to the concealed park position. If so, repeat this process for the passenger side, adjusting it approximately the same amount of space. You may have to experiment a couple of times to get them in exactly the right place.
2. The other possibility is that the park position is screwed up in the wiper motor. I've seen this happen, and actually, it will often go away if you use the wipers frequently for a while. The other option here is to get another wiper motor.
Question from Gene (1975):
How do I get to the windshield wiper linkage connection point: left side, link from motor to wiper arm assembly (the linkage between the wipers is OK). I have removed the plastic grille as instructed in the shop manual but can't find a way to get my head in a position to see the connection point. I've tried a small inspection mirror but hope there is a better way! Even if I find a way to see the connection point, I'm not sure how to get to it to install the clip, etc. I can't even feel the point. I did find the pieces of the broken plastic clip. This may not be a 1975 unique problem (may be 1974 also).
Reply from Elijah:
I remember performing this task on my Grandmother's '78 New Yorker a couple of years ago. I also remember a high level of frustration. I can't quite recall what all it took to make it happen, but I think that I had to remove the chrome strip at the bottom of the windshield, then remove the driver's side wiper arm, disconnect the linkage between the two wipers, remove the three bolts holding the driver's side mechanism in place, and then take out the whole thing as an assembly. I seem to recall that I had to remove the armatures at the end of the wiper motor as well. I know that sounds like a lot, but I remember getting it all done in an hour or two. It is not easy to get to where the clip fits on -- that's why I took out the whole assembly, put on a new clip (why in the hell they used plastic for that...), and then put it all back in at once.
Follow up from Gene:
Haven't had nerve to tackle this job again - yet. But in a day or so I'll have to! Do you remember, did you have to remove the hood to see what you were doing?
Reply from Elijah:
I did not have to remove the hood. Now that I think about it, it might have made the job easier! But I think that you can work around it.You just have to be flexible and enthusiastic!
Follow-up and Tip from Gene:
I finally got up enough nerve to tackle the wiper linkage problem on my '75 Imperial and learned a lesson - again: The shop manuals, good as they may be, are often seem to be written by people who have never had to do the job! But this job turned out to be a lot easier than I tried to make it! The manual just says to do it! But it immediately becomes apparent there is not room or visibility to just do it! I should have my wife take a picture if my 6' 4" frame laying across the engine trying to see and reach the wiper linkage pivot points! Removing the trim strip below the windshield is a help but there is the problem of getting tools in the cramped space to press on the new bushings -- Soooo -- After several hours of fussing, muttering and trying every tool I own, I stood back, said a brief prayer, and rested for a few minutes.When I went back to the job I had a real Ah-Ha moment -- it was clear how to proceed!At the risk of boring everyone, but in hopes it will help someone, I'll try to describe the entire procedure.There are a few steps the manual fails to mention! CAUTION: As pointed out by Bob and Robyn Clark, do not remove the hood unless you have help and are prepared to deal with some rather imposing torsion bars!
1. Open the hood. (how much more basic can I get!)
2. Remove the sheet metal screws holding stainless trim strip at the bottom
of the windshield and slide the strip up about an inch. (This may not be necessary but I think it helps).
3. Remove the washer hose from the clips on the left plastic grille covering
the wiper mechanism.Remove both plastic grilles .They snap in place.
4. Carefully remove the drivers side washer hose from the plastic tee (about three inches away from the arm). (This step may be out of sequence,but should be done before the arm is removed to avoid damaging the hose.
5. Remove the windshield wiper arms. The manual is OK here - once you understand how the arms are made.But for clarification: Turn wipers on, then stop them anywhere near center by turning off the ignition switch (or, if the link between the motor and the left arm is not connected - like mine wasn't, just move the arms to a convenient position. Lift the arm and wiper away from the windshield. Gently pry the little clip open (it is right alongside the arm attachment point). NOTE: the clip is captive - it does not come off - it slides out about 3/16 of an inch. When the clip is out far enough it releases the arm AND locks it away from the windshield. When you get there you'll understand what I mean. With the clip out and the arm
locked, you can remove the arm with a rocking motion just like the manual says. The right side arm still should have the washer hose attached so just carefully lay it aside where the hose won't be damaged. (You can remove arm, hose and all if you want and get it completely out of the way.)
6. Using a 3/8 end wrench, remove the nut holding the arm that connects tothe wiper motor.This is the most awkward step - an inspection mirror is needed, along with the ability to work backwards (looking into a mirror). The nut is very similar to a Tee-nut but without the points and comes off easily. If you don't know what a Tee-nut is, forget what I just said, it isn't important!< Slip the arm off the wiper motor shaft.
7. Using a 5/16 socket, remove the three bolts attaching each wiper pivot assembly.
. At this point you should have all the linkage free (if not, figure out what I forgot and remove it). Slide the assemble to the right far enough to allow it to be removed through the left opening.
9. With the linkage out and on your workbench, change/replace the plastic bushings as required.It's easy now!The manual says to use Channel lock pliers to press on the new bushings but I used a wooden mallet and a back-up block, with holes as needed (to support the assembly without damaging it) as I FIRMLY tapped the bushings into place (They require a bit of friendly persuasion).
10. Put it all back together in the reverse order and you're all done.
Note: When putting the left arm on, be sure the hole in the small arm (that pivots the blade) goes onto the pin at the right side of the arm pivot. The end of this little arm and the pin are covered by a piece of metal that is part of the main arm so it is a little hard to see unless you are looking.Also, getting the wiper arms on in the correct position so they park and overlap correctly per the specs in the manual may take a few tries. when putting the stainless trim back, make sure it lays as smooth against the windshield as possible so the wiper blades don't hang up on it trying to reach the park position. This may all be obvious to some, but I don't think I am a complete novice (having worked on all sorts of cars for nearly 50 years now), and I wrestled with it quite a while, taking the manual at face value, trying to repair the linkage in place. Maybe this will prevent someone else from making the same mistake!
Question from Neil (1981):
The delay feature on my Imperial does not work. I have not looked in the manual yet. Anyone know if the delay is an easy fix?
Reply from Dave:
The wiper delay box is under the left side of the dash it's green in color and is held in place by two 5/16 screws and is a pain to get to as they go in from the top. You can try to get to them but because of the wire harness and fuse block are in the way you may end up getting cut by some of the sharp edges up in the dash. This may sound funny but it's easier to get to if you take out the gauge cluster. If you haven't done this before there are two 7/16 bolts that hold up the steering column. Loosen them but do not remove, remove the headlight knob, remove cluster trim pieces and pull the top of the cluster forward and disconnect it and the head light switch. If you have the moon roof or rear defroster just let them hang down. If this how you do it just to the left and above where the headlight switch is you will see the green delay box. It's the same part used in the Diplomat/Fifth Ave/Fury M-body cars. I have one out of an '87 Fifth Ave in my '81 Imperial now and they both had the same part number stamped on them. Also this is a good time to inspect the headlight switch connector. These cars tend to have electrical problems with the headlights and this is usually the first place you're going to see trouble. I have seen four other Imperials incuding mine that have had burned switches and connectors. So far it's cost me $400 to repair this problem.
Follow-up from Neil:
The wiper link (3799537) with the silly plastic bit that falls to bits only during a torrential rain storm has broken on my '82.
I have made a temporary repair by cutting off the stud that hold said silly bit, migged in a bolt and, mounted a repair washer either side of a bearing roughly the size of the hole the plastic bit goes into in the long link arm (if you know what I mean).
Assembly is one washer on bolt followed by bearing followed by link arm then captured by second washer then nyloc nut pulling it all together.
This when well greased works fine but with no park facility.
I have been quoted £54 plus 17.5% tax which works out to $92 ish US which seems a lot of cash for a small link arm.
Reply from Dave:
All of the body cars used the same wiper delay box. I don't know if it's still available new ( '87 was last year of production ) but every New Yorker, Diplomat and cop car I've looked at in a salvage yard had one.
Question from Ed (1981-1983):
I am having some problems with the wipers on my car. A few months ago I replaced the wiper motor with a rebuilt one from Auto Zone. The old motor would "stall out" when operated on high speed, as if it was popping the circuit breaker; the wiper would stop, seemingly the c/b would then reset and then the wiper would continue, and then stop again, etc...So I just changed the motor. But to my surprise, that problem has continued. Also, the intermittent wipe stopped working. When the wipers are selected to any intermittent setting, they will move half way up the windshield, stop, and then begin operating continuously, with no delay. I replaced the wiper delay control module while under the dash today, but that did not correct the #$^%@ problem! SO I have reinstalled the old module for now. Is this a problem with the motor? Did I just get a crappy rebuilt one, or is it perhaps something else???
Your wiper delay module and motor problems sound quite mysterious. I wonder if there is some poor ground connection, either on the delay module or at the motor. I have occasionally noticed a reluctance to park, but turning them back on again and then off always makes it work right, I assume this was caused by a poor connection within the motor on the park contact.
I think you may have wiper gear box problems. Mine acted similarly to yours last year and the repair shop replaced the gear box, at least I think they called it a gear box.
The wiper problem sounds like it could be a bad ground. I had problems with erratic operation & found that the switch was a bit loose. After tightening all was fine.
Tip from Ed (1981-1983):
I was driving in a local tour last month when a line of rain and thunderstorms moved through. As the rain ended, I turned off the wipers and KLANK---PLUNK, and they parked. That was the end of their action. What had happened, which I have seen on both of the other Chryslers that I've owned with this system, is that the Drive Linkage from the motor to the left wiper, had fallen off of the motor linkage, due to wear of the plastic assembly that holds it on. I also needed to replace the motor, as it was intermittently failing to reverse and park the wipers; this too happened on my other cars, so I did not even bother to check the wiper switch, as I was sure it was the same failure again internally in the motor.So I've got all the genuine MOPAR parts I needed, including a new MOPAR wiper motor and put them in today! Boy, I really skinned some knuckles with this task. Anyways, the wiper arms are attached to the pivots with this clever little locking device. To unlock it, you must lift the arm up off of the glass and then slide the locking tab up---This all came back to me VERY SLOWLY Well, I found that the left (driver's) side arm did not have this locking device on the arm. You could see that it was once there, but must have been broken off under previous maintenance.Nonetheless, it was a real PAIN toget that one off. It was really on there tight. I got everything all back together, but now I am worried that that left arm may come loose at an "inopportune" time. I'm afraid that by removing and replacing it a few times as I got the arm placement adjusted that it will not be as securely attached as it was before. Does anyone know if there is a repair kit or something for that locking device; perhaps I could drill out the rivets and screw in a new one.The arm is in very good shape, and I hate to go to my friendly MOPAR shop only to have them tell me that I must buy a new arm (if it is even still available.)
Question from Trevor (1981-1983):
It appears to me that the nylon brush, about 2 inches in diameter, has broken at the center where it locks onto the linkage which goes to the driver's wiper post.
Does anyone have the nylon brush? The part number on the brush is 3799281-32188. If I am able to get just the brush, is it possible to fit the new brush into the linkage without damage or does one have to get the whole assembly?
I believe it was this same part that failed on me driving on a Sunday through New England during the 1996 hurricane.I was able to order the part through a dealer, and he only had to replace it, not the whole assembly.
I have had to replace this linkage on both my 81 and 82 Imperials, as well as on my 80 Cordoba that I sold some years back. In all cases, I replaced the main linkage arm, which is sold as an assembly, since in all three cases, the nylon part where the linkage attaches to the motor had failed; it does not appear that the nylon part is serviceable as a separate unit. In any case, I found the part still available at Chrysler a few years ago. If you cannot find it there, go to Parts Voice (Link is on the IML homepage, I believe) and enter the part # to locate it. I have had to replace all three of those cars' wiper motors, too, so if yours is performing weakly, I would suggest you replace it too, while you have it all apart.
Question from Gary (1981-1983):
Yesterday I switched my A.C. on high and I smelled plastic burning (briefly) and now I only get low speed (no burning smell). The wiper speed only works on one speed (low) intermittent is fine. The "miles-odo" is reading : __ __ __ __ (dash's) instead of the actual miles on car.(trip odo.is fine). Are these problems related? The car drove about 1000 miles round trip to Carlisle recently without a problem. Any ideas?
Reply from Dick:
The wiper speed problem could be in the wiring harness, the switch, or the motor itself. First thing I'd check is the wire connector at the base of the steering column and at the wiper motor. Maybe you just have a loose connection. If you look in the FSM, you can identify which are the wiper control wires are.
Question from Dan (1981-1983):
Last night it was POURING out when I left work. I jumped in to my trusty Imp, started her up (runs WAY better now on fast idle, with Dick B's help) turned on the wipers and CLUNK!, I hear what sounds like the drive shaft fall into the plenum. No wipers! Great! I get back out and grab the wiper, they both move REALLY easily! So, now soaking wet, I carefully pull out and head home. At least the two-year old Rain-X still works when I hit around 45MPH or so. Think it's the shaft connecting the motor? I can hear the motor run. How hard is it to get at, and could it be a bolt that came loose?
This is a common failure with these cars. The somewhat goofy looking coupler that connects the wiper motor to the relay links has come apart due to failure of the plastic part which holds it all together. These are fortunately still available at your friendly local Chrysler dealer, because the parts are apparently used on many years and models of cars.
The parts are easy to change, and require no disassembly other than to remove the wiper arms from the stanchions, then open the hood and remove the plastic bug/leaf inlet grilles over the air plenum in front of the windshield. You must use extreme care with these 20 year old plastic parts, as they are brittle and will break at the slightest insult. This caution applies to the windshield washer hose "tee" and couplers also!
Once you have the grilles off, you'll feel a nut (I think it's 3/8") at the end of the wiper motor shaft - you can't see it unless you are over 8 feet tall with the upper 3 feet of that as neck, and can swivel your head 180 degrees. But you can easily feel it, and undo the nut. Be sure you don't drop it down into the air plenum!!!
You'll also have to remove the other end of the relay arm/link because that whole assembly is spared as a unit. The three screws that hold the wiper stanchions are obvious, so this part is not tough at all. Be sure to note exactly how the arms are arranged, there seem to be at least 17 different ways to put this complicated linkage assembly together, and 16 of them will break the new part immediately. (Please don't ask how I know that. Thank you.)
The part number is 3799 537 It is item #8 on page 23A-1700 of the parts book.
Of course, you should verify that this is what is broken on your car, but this is the exact symptom I have had on all 4 of mine at various times, and we don't use the wipers very often out here.
Usually the cause of this is failure of the little plastic bushings that hold the arms on. The arm fits over the little plastic onto the nub of the motor. You can get them from chrysler for a couple of bucks. I don't know of another source. Did it on my '73 Satellite, Imperial is PROBABLY the same. I think it is easier to pop the main one off and attach the others then put the main one back. Squeeze them on with a pliers/vise grip.
Question from Bob (1981-1983):
I need some help on the repair of the wiper linkage on my 81 Imperial. The plastic disk that clips on the wiper motor and holds the linkage broke. I found another one off an 1980 Chrysler New Yorker that looks to be in good shape and be the same part. Should this part just snap onto the linkage and then on to the motor or do I need a special tool to do the job.
You need to climb up where you can see down in there, after you remove the plastic air plenum grilles. Be very careful with the windshield washer hose fittings, they will break very easily. When you get a good look at things, what you need to do will be obvious.
The linkage I think you mean is still available new from your local dealer. The disk as you call it is actually quite a sophisticated device which changes the effective length of the power arm when the motor is reversed to park the wipers, that is why the blades park lower than the normal sweep.
These often fail as the cars age, since they are made of plastic. Cars that have been exposed to a lot of sun and weather will fail first, so if your used part is off a car which has been out in the weather all these years, I'd go for the new one. It is under $50.
The part you need to replace is the disk assembly and the lower linkage arm, and to do this it takes no special tools, just the dexterity of a trained elf, the eyesight of a diamond cutter, 4-foot long arms, and the patience of your grandmother. You'll need just those items, plus a strong light, a nut driver (I think it's 5/16) and a socket wrench for the motor shaft, either a 3/8 or 7/16.
I'm not sure if the '80 Chrysler NY'er part will fit. You must buy the right
replacement part - number is: 3799557. It's still avail from Chrysler and is
good for the Dodge Mirada and Chrysler Cordoba, 1979 thru '83.
Get a couple of the nylon end connector pivots also and replace it all.
