Ok so about a month ago my driver side window stopped working and i just got around to messing with it, and I found that when the motor is in the door and hooked up it wont move, (I can hear a click and ive tested the switches so I know they work) but when I pull the motor out and manually hook power to it, it moves like new for as long as its out, then when I put it back together it works for a second then stops again and I cant figure it out. Its doing this on both sides of the truck.

check how much voltage is getting to the motors from the plug in the door. anything less than battery voltage than you have a short.

Motor Repair

Motor Torque Pin (also called Bushing) Info & pic (Tailgate, but same for PW); "...fixed it for free some fuel line and a few small cunks of a bolt. Here is a closeup of the bad parts. in the points of the triangle there should be 3 round pins. this help cousion the window from motor shock. I cleaned all the old grease out of the motor and the final drive. my final drive was fine so i was going to reuse it. To rebuild for almost free here is all you need. some fuel line and some steel rod or round spacer (this keeps the fuel line from colapsing completely) i cut the fuel line to the height of the drive gear housing and cut the spacers from round stock i had on the bench. the steel spacers go inside of the rubber fuel line. then the rubber fuel line and steel spacers go in the final drive gear.this was a tight fit but not too tight..."

ubrication from Bronco Workshop Manual; "...Use Silicone Lubricant C0AZ-19553-AA (jelly) and D7AZ-19553-AA (spray) or equivalent meeting Ford specification ESR-M13P4-A on the door and window weatherstrips whenever necessary. Silicone lubricant helps avoid weatherstrip squeaks and retards excess weatherstrip wear from chafing between the door glass upper frame and the weatherstrip. It also helps to retain door window alignment by reducing friction between the glass frame and the rubber weatherstrip. Use Multi-Purpose Grease Spray D7AZ-19584-AA or equivalent meeting Ford specifications ESR-M1C159-A and ESB-M1C106-B to lubricate door and tailgate hinges. Apply an even coat to all hinge pivot points as outlined in the maintenance schedules or when a binding or squeaking condition occurs..." miesk5 Note, Use PTFE grease for slides & tracks. Use silicone spray on the weatherbelts & glass run; test the silicone on a regular styrofoam cup first; if the cup gets funky or melts, then the can or tube contans oil, a regular occurrence now, esp if from China

When the motors work when not under load, but are not working when under a load, that is an indication of worn contact brushes, and /or the internal thermo breakers are shot. It may not be worth the time to try to clean or repair the motors. I would just get new ones.

Good luck
