Wipers don't "park"

I was going to do a quickie hijack question since you all are on the subject in another thread, then decided not to.

My wiper motor (1975) works fine but the wipers won't return to park. A local Indy says I need a new motor as the "park" feature is part of the motor. Is that true?? If not, anyone one have any suggestions on how to fix it?

Duc,

The wiper switch consists of terminals # 53a, 53, 53b, 53i, 53e, and 53c. During wiper park cycle, 53e (blue wire) is connected to 53a (red/white wire, +12 v all the time). The connection is made when the wiper switch is off and the motor is not in the park position. The motor makes connection between 53e and 53a with an internal disk. The wiper switch connection between 53e and 53 puts the wipers into the slow mode, until the disk inside the motor turns to the park or off position.

53a Red/White = +12 v all the time
53a Black to capacitor and to red/white in parallel = +12 v all the time
53 Red/Black = slow speed wipers
53b black/yellow = medium speed wipers
53i green = fast speed wipers
53e blue = park at slow speed
53c black = washer pump motor

You should be able to clean the internal disk so that electrical connection is made and the wipers will park. I did this about 15 years ago, and my wipers still work perfectly.

OK, someone get this man a beer! I will pull it and try (this weekend hopefully) and report back. Thank you!!!

Most likely it's a bad contact in the wiper switch. Very common problem. Check
this thread for some good hints and tricks:

Also a bad ground can make them stop parking. Check from the wiper through to the grounding stud.

going thru the same problem with my 930.

its not the switch and not a ground problem.

not sure of the details of the 75 but it looks like walter did an fabulous job.
the park function is internal to the wiper motor,.

I have not removed my motor to dig into it yet, not looking forward to pulling it out,.

I just remove the connector under the dash when I want the wipers to stop.
I will do a thread on the motor when I do

Quick Update. I played with my switch. It doest matter how I wiggle it (or hold my face) I cannot make them park. so off to the next few steps in this process this weekend. That will be pulling the motor and looking at it.

Mine wouldn't park either, problem was in the switch. I posted what to fix in the switch in the thread below; scroll down and check out the pictures.

it depends on what you mean by they don't park.

do they keep running? not the switch- motor
they stop where ever they are when you turn them off, switch or other problem.

mine keep running.
my problem is in the motor.

Had the same problem. My car is an 84 and my delay rotary dash switch would not work either. I replaced the stalk/switch, problem solved. Its a quick easy fix.

I have heard part of this issue can be the switch, and part can be int eh motor assembly.

If the rotary disk internal to the motor is not making good contact, the wipers will stop where you turn them off. Jiggling the stalk will not make them continue.

If the wipers keep moving when you jiggle the stalk, then it most likely is the switch in the stalk.

The wiper motor can be accessed through the dash by removing gauges - at least on my old car.

if the wipers CONTINUE to run when in the OFF position then its ONLY the motor.
if they just stop as soon as you turn them off or they just randomly stop, it can be the motor or the switch or connection. start with the switch in this case since it is easier.

Well embarrassingly almost a year later (long story) I was hunting around for answers as to why my wipers wont park again. I stumbled across this thread, started reading it, finding good info....only to discover I STARTED THE F'ing THING A YEAR AGO!

So almost a year later....I pulled my stalk and check those contacts.....they were not connecting, but even when I do it manually no joy. So I bent them so they make contact. I guess my next step is pull the motor and see how the disk looks. Doesn't sound fun to me.....but this car only had a plastic dash pad that takes 3 screws to get out, so I will have better access than most.

Just an update, long over due. I pulled the motor, cleaned everything up really good and re-greased it. Put it back in and wired it up. It was wired improperly before, which I did not discover until re-installing it. Between the cleaning and wiring it up properly at the motor everything works great now, and is super quiet. Great news since the original metal stalk looks proper (vs the plastic later version you now get when you buy a new stalk).


If only I could find a metal blinker, since my blinker stalk died and I had to get the plastic one.

You probably already checked this. But just in case, since the wiper intermittent knob in my 86 and the windshield wiper stallk function independently - I found that my wipers never parked properly when I forgot to turn the intermittent knob all the way over until it clicked off.

Just to clarify. I would run into the issue in light rain, I would turn on the intermittent wiper knob. Then it would get heavier and I would click up the stalk to start the constant wiper, and forget to turn off the intermittent. If it stopped raining, I would click down the stalk to turn the wipers off - they would stop, but not park.

As long as my intermittent was all the way off, they parked fine. Not sure if this is normal. But works fine for me.
