My windshield wipers are stuck in the upright position on my 2001 Pontiac Montana and they wont return to the right position. They work fine when I‘m using them, but when I turn them off they return to the upright position. I took out the fuse, and that is not the problem. Any ideas on why they would stay that way and any suggestions as to how to fix it would be great.
Well there is a sensor that tells the motor where to stop and that could be faulty also the wire going to it could be bad , the sensor is on the wiper motor or built into it. What I'd do is go to a U pick auto wreckers pop out another wiper motor for about 10 to 20 bucks,or buy the whole wiper motor and linkage assembly and switch them , or just get the motor and unplug your wiper motor try just plugging in the used motor , run the wiper motor see where it stops , compare it to the wiper motor on the vehicle , you might need to remove the grill and wiper arms to get a close up look and check when it's plugged in and stropped where it's arm stops. Hope that helps and best of luck.By the way it more then likely is the wiper motors stop position sensor.
You probably have moisture on the circuit board that is bolted to the wiper motor. You can take it off and clean it with electrical contact cleaner and reseal it with a little RTV when you put the cover back on. That is the same problem I had with mine. I found a new motor and board at NAPA for $80.00 but tried cleaning mine first and it has been fine for 4 months now. If you do try to clean it make sure you mark where the wiper cam and wiper motor shaft so you line them back up right when you put them back together.
