On my 97 Jimmy the rear wiper stop working. It would only work when you gave it a push with your hand with the switch on. I took the motor apart and cleaned up the contacts and lubricated the gears. Put it together.................now it works and works really great...............big problem is it only works with the rear hatch glass open!!!. Any help would be appreciated. The actuator works well too. No issues there.
Thank you
James
