the shaft on the wiper motor is stripped...pull the wiper arm off and check it...
I wish I would have read this first. Would have stopped me from taking my dash apart to check voltages at the wiper switch!:bonk:Just a word from a very inexperienced envoy owner---remember every time you test to see if the parts you are replacing, have to be done with the tailgate properly CLOSED
My problem was in the harness at the top wher the hindges are--pulled out the grommet an the broken wire we found was the only thing wrong. Spliced and works fine.
you would have better luck over on the other site getting answers.. follow the link HERE and get welcomed to the promise land.. unfortunately the site is down for maintenance at the moment, but for sure check later today and join over there..I checked for corrosion everywhere that I could check. My rear wiper works if I pull #9 fuse and reinsert it until I shut the vehicle off. As soon as I shut off the vehicle and the door opens killing all power, the rear wiper will not work again unless I pull and reinsert the fuse. It is like the fuse getting pulled resets something somewhere? Any ideas would be great. I checked for frayed wires etc but it is all in good shape. I replaced the wiper motor, the dash switch and all the relays. The rear washer pumps correctly and the fob works. Rear lift gate unlatches correctly etc. Rear defrost is fine. It's just the motor that acts up. Please help! I checked the ribbon wire in the module under the seat in front of the fuse box but it looks good to me. Thank you!
