Cant find answer to window issue

after looking further the bushings in the motor were gone. Kind of think replacing those, guide bushings and grease job should fix it. ??

Yes, you need new window guide bushings. Very easy fix. The driver side usually gets twice or maybe even three times the use as the passenger's side. Dont be surprised if your power window motor goes out soon as well. Amazon sells an inexpensive one as compared to other Mustang product supporters.

Power Window tips & tricks

Motor removal & replacement
Remove the door mounted speaker & the upholstery panel to gain access to the motor. There are 3 screws (5/16" hex head, I think) that secure the motor in place. Remove them and the motor comes out without any problems. Once you remove all the screws from the motor, and it falls away from the gear teeth on the arm for the glass, the glass will move up and down. You may need a helper to hold the glass once the motor screws are out, since the gear on the motor holds the glass from sliding up or down

Motor interchange
The motor is the same for left side or right side, only the gearboxes are different. If you can't find the complete assembly for the side you want, you can get either side and use the old gearbox on the new motor.

The window motor gearbox has 3 plastic rollers that are a safety clutch to prevent possible injury if the window is rolled up while something or someone is hanging out the window. The plastic rollers will often disintegrate into chunks of plastic and the window will no longer roll up or down. The motor runs, but the window does not move or only move a little.


The Help! section of your local auto parts store will have the replacement plastic rollers.
