I just purchased a 97 Impreza Sport Wagen and discovered that the rear electric door lock and the rear wiper don't work. The lock works with the key in the hatch, but not when locking the other doors. Strange that the rear washer sprays, but doesn't activate the wiper. I did look for a blown fuse. It would help if I could find a wiring diagram.
If I open the hatch about half way the wiper will start working. It wont work at full open. If I work the hatch up and down a short distance it will work when closed--IF I close the hatch extremly easily!! Sounds like a bad ground to me.???
