Computer needs to see park sense signal sent by the wiper motor. May be a bad motor internally.

Also I have read of ground issues. One is the ground connection next to the drivers side hood hinge. Also a ground issue at BCM pin#6 and pin#8.

BCM- Body Control Module

In essence it is a computer that is like the pcm, but contols non- engine performance things...like wipers, lighting, locks etc.

Mitchell does not provide a location. Alldata may. but I do not have access until Monday.
