Wipers not working correctly

[Bill Meerholz]

Sorry but no not clocked correctly. 1 st piticture was not so clear . Yes should be clocked where blue arrow is. Like in picture i sent.

If you haven't done it yet, here's what you'll find under the top plate.

Thanks, good to know what to expect. Have not done it yet, car is put away for the winter! Will get to it sometime, hopefully soon.

OK, well that switch must likely be what's wrong with my motor, since i tried the grounds. I assume that top plate can come off the motor while its still on the car?

Yes top plate can come off in car , but 2 wires are soldered to switch. But also could be one of the tabs on top face of the gear may be broken. Even if small potion of either tab is broke off will not park. So may need a new gear.

OK so here's my wiper motor. It doesn't have the standard (type) of motor the way other pictures here have, but I assume its an aftermarket? Or just an early model?

Does anyone know if I can get to the home position switch by popping that cover off with the two screws, which looks like it'll get the whole (cylinder) top cover off the motor?

That is a 2 speed motor - this thread has been all about 3 speed motors.

Thanks Steve, yes, it is 2 speed. Is that very different when it comes to the home position switch? And can it still be serviced attached to the car?

 

[Steve340]

Sorry I don't know anything about the 2 speed.
It may pay to start another thread?

Yes, definitely start a new thread. You'll get more responses and more specific to your needs. Maybe something like: HELP - Two Speed Wiper Motor Not Parking

Hello all,
I've had my 71 Cuda for a few years now, when I bought it the seller told me the wipers did not work, he had the motor rebuilt (or replaced, I forget), but they did not work. The wiper arms were mismatched and not great looking, so I took them off. I never drive in rain, so not really an issue. Well, I'd like them to work. I took the grilles off and cleaned up a bit in there, but it was pretty good. Sprayed a little silicone on the couple of joints I could see. I assume the fully counter-clockwise position is off/park. When I turn to the first detent, the mechanism seems to work OK. At the second detent, it either stays the same, or just stops. The third detent does nothing. Back to first and it runs. Back to off/park, it reverses direction and parks (like I think it is supposed to).

View attachment 130086Does this seem like a bad switch? Is there a way I can test by doing anything with the wires on the motors gearbox (there are a couple of wires there)?
If it is the switch, how hard is it to swap? Any general guidance? When I've loosened that section of the dash in the past, it doesn't pull out very far to allow access to the connections (or even see them).

I'm attaching a photo of the motor and a video of the mechanism running. Thanks for any help! I guess I don't know how (or if you can) to attach the video.

Get yourself a service manual and go to the electricals. Section, go to wiper motors. You will need 3 jumper wires, and you can test your wiper motor by the using the battery, not the switch. I did it on my 70 barracuda. With a two speed wiper motor and I fixed it. By the way, you have to test the ohm's on the ballast resistor the ohms should be between 1 and 3 Ω. Anything lower or higher means you need a new ballast Resistor

Also, you might want to try cleaning all the connections on the back of your switch, which will be a pain and a butt to get to without taking off your instrument cluster on the left side where the three switches are. I also cleaned all the connections on the front of the bulkhead connector in the engine compartment

I have a wiper question too on my 72' Cuda. I hate these factory wipers especially the drive side with the helper armbrace that's attached to the car and the wiper arm, it is tearing up my windshield molding at the bottom of the windshield. Is there an after MKT windshield single wiper arms and blades I can buy that will work instead of these factory one. Of course for both sides. Thks in advance.

[Bill Meerholz]

Problem with your original left arm is the pins in the swivel piece where blade attaches are worn out & the swivel part has worn oblong holes. Also may have the lower moulding missaligned (not flat enough to the windshield). Lots have same problem. As to after market never heard of ant but there repros available , how good don't know. But at least not loose.

The factory service manual is a big help for testing the wiper motor with just the car battery and a few wire leads. It's in the electrical section and look up wiper motor. Very simple!

 

[AUSTA]

Both the motor housing & the switch must be well grounded when you turn the switch to off it reverses the polarity on the field winding causing the motor to turn backwarks until the park switch on the motor plate opens ,If the wipers hit the chrome window strip or the edge of the hood it will stall & the overload switch in the wiper switch will click continuasly until the fuse blown's or they motor burns out.
The stop position can be adjusted by turning the stop plate on the motor there is 2 small locator or by moving the wiper blades
