power window repair

Post by tallakguy »

My driver's side power window ceased to operate. Passenger side works and can be operated from driver's side. Any clues on how to repair?

First question is whether it's the switch or the motor. Unfortunately I don't have any experience diagnosing those specifically, but I'd look to see if you can swap in the other switch to test it.

swap in the other switch? by switch i assume you refer to the gizmo located on the arm rest part of the door? motor is located who knows where. I thought maybe a blown fuse, and wonder if each window has its own fuse. Fuse box is located within the engine compartment and mighty difficult to access...

I meant the switch from the passenger door, just to test it.

I doubt they're on separate fuses, but it's possible.

I'd be happy to help if you need it - DM me. I've rebuilt one motor, replaced the other, and replaced both switches on my '90.

The switches aren't swappable - the driver side door has switches for driver and passenger window, the passenger side has switches for just the passenger window.

When you press the window switch, do you hear anything happen? The nylon gears in the motors can fall apart - you'll hear the motor spinning, but the window won't move. If that's the case, you just need the new nylon gears.

If you don't hear anything, could be power or the motor itself. The motors can seize up - a good whack on the motor with a hammer will sometimes get a few more up/downs out of it. Or could be power - but the fact that you can still control the passenger window makes me think power isn't the issue. My guess is the driver's switch is bad. The replacement is 901-305 Dorman - it's a different appearance (I think it says it's for the Astro van) but it fits and works.

If you have a multimeter, take off the panel to get to the motor. You can test for power at the motor itself - pressing the switch will give you either positive or negative DC voltage (one makes it go up, the other makes it go down). If you get power at the motor and it doesn't work, you're motor is bad. No power, switch is bad.
