87 Mustang, power window broke

The left side rear power window won't go up or down. It sounds like the motor is moving, the window wont' move. I tried to force it down while holding the switch and it didnt help. How can this be fixed or replaced? Thanks.

Howdy! If you haven't already, your best bet would be to remove the interior door panel to see if a part of the internals is broken or has simply worked itself loose.

I've never worked on a mustang before, so I wouldn't be able to tell you exactly what to look for... but, one of the best "parts" I've ever purchased for my acura was a Haynes repair manual. You can find them at most auto parts stores, and they're a really big help.

Before I had a repair manual, I replaced all four speakers and the head-unit in my car, and at the peak of this project, you could see the transmission from the driver's seat, lol. Usually, door panels are attached to the door by a combination of screws and plastic clips, and the plastic parts are easy to break if you don't know where they are.


*edit* I did some googling, and apparently, if you take the interior panel off it's still not a straight shot to the power window motor; but the gear-teeth on the motor tends to wear down and might be part of your problem...

it may have a gear kit available for it, that will allow you to replace the plastic gears that strip out and not have to replace the motor.
check with your local parts store.
