So I followed advice of members here. Thier thinking was along my lines, I had just washed the car, then 1 minute later the wiper starting going on thier own, then the washers started spraying on thier own. So I went after the wiper control module located right on the wiper motor.
I removed the wiper cowl and wiper motor and trans, removed the module from the motor and cleaned with electical contact cleaner, and ran a small bead of RTV around the edge of the module case in hopes of keeping water from getting in, cause it did, not much junk buildup on the module, but did have water sitting around the connector and motor area.
Anyways, threw it all back together, reinstalled wiper motor fuse (7.5 amp under steering wheel) and plugged back in the washer pump, 3 minuted later they started on thier own again.
I callled the local FOMOCO and priced the module, not available seperate from wiper motor.
So its $160 + tax I guess unless anyone has any other ideas.
Guys???
