Can somebody solve this issue for me? The rear windshield motor runs but the plastic gears were stripped. Replaced with new motor but it would not work. removed and hooked it up to battery and new motor worked. Again hooked it up to the harness and it worked. Shut it off and mounted the motor. It will not run. washer pump works fine. This makes no sense to me!!!! Can someone suggest what could be wrong. Could there be a problem with the circuit board attached to the pump harness?
