Another example of insanity..

My wipers stopped working so I took the electric drive motor out to clean the contacts as a possible solution.

This has to be one of the dumbest designed contraptions in history.

Lord only knows if it will work when I get it back together. geez......

 

Might need a replacement wiper motor for my '87 XJS. Any leads?

I was hoping I could use one from an XJ6 but it appears that model uses a completely different set up. I have no idea where the wiper motor is. Possibly behind the dash. How smart would that be? (sarcasm)

See my recent post in the classifieds (For Sale, Mid Atlantic) for a set of Dayton wire spoke wheels. Lots of other stuff as well.

 

Whats wrong with your motor that necessitates replacement? Excessive resistance in the windings?

 

Take the entire motor apart. Not too hard to do. Keep track of everything position. They corrode up inside around the armature and brushes. Be carful of the permanent magnets. They often come loose. They can be epoxied back into place.

The easiest thing to do is to buy the later Electrolux wiper system from a breaker (the entire thing including the grille). This later system is far, far better. It is a direct drop in replacement EXCEPT you lose the intermittent wipe. This can be fixed by doing something to the column switch wiring, but I lived with it.

I don't know why it wasn't working which is why I took it out of the car as well as have half my steering column pulled part to get to the switch.

With the motor out I applied 12V to the various spade terminals on the plug (properly grounded of course) to see if I could get any action from the motor. I did not leading me to speculate that the issue probably resided in the motor, not the switch.

I took the motor apart very carefully laying everything out in the exact order and direct. I drop the circular metal piece with the T-shaped arm with the angled ends. Not 100% sure but think the tips should point away from the plastic plunger arm stick thru from the plug housing. Guessing it is somehow associated with the intermittent function.

I cleaned off all the contacts and inspected the brushes. They don't appear bad but don't know for sure. I have no idea about the windings.

Only issue on reassembly is getting the spring to fit down into the lipped ring of the drive arm. I also need to replace the very thin metal gasket since it split. This is part of the spring, washer, thin springy gasket and finally retainer "C" clamp on the drive arm.

 

I'm with Greg, the later wipers did away with the unreliable cable drive and went to lever action, I'm not sure when this happened but my 89 has the later wipers.

 

Any idea if the '89 and up model will interchange into an '87. Electrical connector, mounting bracket, wiper arm alignment, etc...

I found a replacement Lucas motor that has been bench tested so I am not dead in the water if the later model is not compatible. Thanks,

thanks. Sailed right past me the first time.
