2nd Gen Non-Engine/Transmission Wiper arms stop in middle of winshield when I turn them off.

Hey guys, anyone have this happen to them? When I turn my windshield wipers off the will stop wherever they feel like it on the windshield instead of returning to the bottom where they are supposed to. Is there an electronic module that controls this?

I believe there is a set of contacts mounted on/in the wiper motor that are opened when the wipers get to the park position. If the contacts are bad the wipers will stop whereever the swuitch is turned off. bg

I used to have this happen on my truck. I would check and clean all of the grounds on the truck, especially in the engine area. If there is a grounding problem the wiper motor stops where it is.
The wiper motor and my exhaust brake used to stop working off and on when it was hot out. I separated the two and put them on different circuits, cleaned all kinds of contacts on both the exhaust brake and the wiper motor. Seemed to work for a short time only. I ran a second ground line from the exhaust brake controller switch and cleaned all of the grounding straps in the engine compartment. The systems have been trouble free for the last 4-5 months or so. In 113+ F and the brake/wiper still worked without a problem.
I would clean and check all of the grounding straps to start with. The wiper motor needs a path to the ground to move at any time.

Ok thank you guys for the help. I'll pull the wiper motor, see if I can clean / inspect those contacts and check the resistance I am getting on the ground path to it.
