Power Window Not Working?

Gearbanger 101 said:

Swabbing the terminals with a littel dielectric grease will help extend their life a little, but I agree with 91TwighlightGT. Its only a matter of time before they fail again. I wasted my time with the window switches on my F150 (a common issue) before just breaking down and buying new ones.

Wellllllll, sh$%.

Plugged my passenger switch in today and.......nothing.

Guess I'll try and buy a new switch to see what happens.

I have the same thing going on. The passenger side switch goes up and down on both doors the driver side window don't go up or down and the unlock switches on both won't work either. What could be the issue?

The answer will cost you a properly punctuated and corrected question. Please correct the grammar & punctuation and repost.

Thank you for your re-write; now it is much clearer.

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.

Stuck with door lock actuators that don't work and don't want to pay the $50+ for a new one? Tried the junkyard ones and found that they last six months and freeze up?

A new actuator for less than $7. Fix one side for $20, do both sides for only $28. I don't sell parts, I don’t make any money off of the upgrade, I just tell you how to do it cheaply and easily.

By the way, I am still using the same $4 actuators I bought in 2002 and this is the second Mustang I have installed them in! Beat that with your fancy replacements!

My drivers window started working intermitanly and I took the motor out, tore it down and cleaned the armature . Worked for a while and quit again . So I bit the bullet, ordered a new motor from Rock and now it works just fine. Replace your motor.
