I've been really lazy, as this failed months ago, but I finally got around to it today. I'm baffled. Car is an '87 is. Here are the symptoms:
- Pass. side power window does not work
- Drivers side window works
- Sunroof works
- Passenger side window switch lights up
What I've tried:
- Reset the power window breaker on the dash
- Checked the fuse for the power windows
- Swapped driver side switch with passenger side switch
- Tried a "known good" used motor
I figured it was just a motor, so I bought a used one that was tested and proven to work. Right now, I have the door panel off, the moisture barrier off, and the motor out. I've tried both the original motor and the known good motor. They both do exactly the same thing. When I hit the switch, I hear a small click in the motor, but the gear does not move. I can move both motors with a 4mm hex in the emergency roll up socket in the motor, so I know both motors move relatively freely.
The culprit is likely a wiring issue, but I am simply not good with wiring. I searched for similar "one side works, one side doesn't" threads, but didn't find much that was useful.
Thoughts and suggestions?
