A month ago my rear washer wouldn't shut off. I had to disconnect the battery to get it to stop. Replaced the fuses and it didn't happen again until yesterday. Wiper turns on by itself and rear pump screeches and then shuts off, then on. Afraid to let car sit with battery connected if it comes on while I'm working and it drains my battery. Anyone else have this problem?

If you can remove the steering column trim to access the wiper switch pack connector. Wait until it fails again and disconnect the connector to see if it stops. If it does, it is most likely the switch pack (Stalk) If you can determine which and where the circuit relays are, you can shut it off there by pulling the relay (s) and also do some diag at that point. Good luck.

What year is it? My front and rear wipers and washers are controlled by the same switch pack. (The R/H stalk on the steering column)
