windshield wiper motor assembly

Post by miker » Thu Sep 12, 2019 9:13 pm

I took apart my windshield wiper motor to fix slow wipers, and found that the contacts that control parking were corroded. So I used some garnet paper and fixed that. When I put the motor together, it worked, but there was this small nylon piece that sort of rattled around and whose function is a mystery. Then I found a spring on my workbench whose role in life is a mystery. It seems to go between the nylon piece in the upper right corner of the photo and the black plastic piece that has the wiring terminals. Does anyone know what purpose this spring serves?

Now the motor doesn't work at all. See newer post about adapting a 128 motor to the Spider.

I don't have a wiper motor apart but I think:
there is a space at the end of the motors worm gear for the wedge to fit. Small edge down. The spring applied pressure on the wedge. The two parts limit the end travel to the motors shaft when it starts and stops.

The motors ground wire is attached to the motors case by one of the cover screws is it making a Good contact???
