Windshield Wiper Motor Switch
Rebuilding the windshield wiper switch is simple and straightforward. Special thanks to Derek S for providing the photos.
Since I don’t know what’s what at the motor end, I can’t really explain what’s going on here, exactly. Something looks odd on my FSM wiring diagram, so this is my best guess until I can do some more research.
Pushing the windshield washer switch puts +12V from the fusebox out to the pump.
