This was working just the other day. Washer squirts fluid. I can hear the relay under the dash click when I press the switch. Little light on button does NOT light up when washer is squirting out which it used to do. Wiper is not "stuck down" and does not move. I _assume_ this means the rear wiper motor has went to the big electronics pile in the sky.

Question: Is this the same wiper motor which was used in the 1990 Grand Wagoneer? I have one of those motors lying around. Didn't want to take things apart until I had the correct motor.
