my wiper motor will not park. I cleaned the switch, contacts, added a good ground. nothing changes. inside the motor, there is nothing but the electric motor and gears. aside from the fact that it is riveted together-I cant see anything to fix. the motor has never been out of the truck and has not been used much [no rain in AZ].
what am I missing?
thanks Rod in AZ

I took one apart several years ago and the park mechanism is part of the gearing. There does not seem to be anyway to fix them so my suggestion would be to pick up another wiper motor if you have checked all the grounds. I have only had one wiper motor fail to park. I assume that you made sure the switch was grounded and you are trying the park feature with both wiper blades installed.

Info I have saved off another site and a link.

The park switch is inside the wiper gear box.

The paragraph that relates to this problem:
If the motor stops immediately when switched off (doesn't return to park position), first check the motor's ground strap. Since the motor is mounted on rubber cushions, it's grounded via a copper strap attached under one of the mounting screws. This is the ground for the park switch so the parking feature won't operate if the ground strap is missing, dirty, or corroded. If the ground strap checks out okay but the motor still doesn't go into park then the problem is most likely a worn out or dirty park switch. The park switch is located inside the motor's gearbox so some disassembly is required to check/clean the switch. I recommend consulting a good repair manual for the motor disassembly procedure.
