Its been many years I haven't used the wiper motor on my GT4 probably 16 or 17yrs . I had my column switches repaired by Verell early this year. When I tried the rebuilt stalk ,the wiper did not work , so I figured id get around to it. Well this weekend I did. Surprising what I found was the problem. And Btw photos to follow . I searched for photos and found nothing, so now future torture patients will find some. Mike
the grease wasn't hard but there was barely any in the housing. And the grease that was left was coagulated and wouldn't even stain a rag. Next up was to un solder the Red to Blue connection and the Green to grey connection to separate the body from the gear housing. only two screws need to be removed to separate the two halves.. Btw note the mark on the gear and "cam" with the dot pointing to the screw hole with the small dot next to it

I tapped them free and cleaned with break clean and actually sanded the two stuck brushes with some 400 paper,barely.

Take a photo to make sure the brushes touch the armature Also a photo of armature in body. Removed it easily.
My write up isn’t great but there aren’t many parts. I really wanted to post the internals/ since I didn't find any pics through search.There is a small o ring at the output shaft u should be aware of and some Mickey Mouse looking spring that holds a small metal cover around the output shaft
