So my rear wiper started on it's own and the washer fluid started spraying? I removed the rear motor yesterday and the outside has corrosion. A couple of months ago, my windshield wipers started on their own. I had to remove the motor, clean the corrosion from the circuit board and it worked like a charm. I had to pull 2 fuses to try and get the rear wiper and it still started on its own, but atleast the fluid wasnt spraying. What do I do? Does the front motor have anything to do with the rear wiper? Should I buy a rear wiper motor? Thoughts?

I don't know if this will help, but when I had some water getting in through the hazard lights on the roof, the water sat in the ledge on the driver side door. (covered by the plastic step cover.) When I had about a 1/4in of water there from parking on an incline my back wiper went of by itself. Not sure if this can help
