'91 F-150 - Removal of power window unit

Disconnect the battery ground.

Remove the door trim panel.

Disconnect the window motor wiring harness.

There are 2 dimples in the door panel, opposite the 2 concealed motor retaining bolts. Using a 1/2 in. (13mm) drill bit, drill out these dimples to gain access to the motor bolts. Be careful to avoid damage to the wires.

Remove the 3 motor mounting bolts.

Push the motor towards the outside of the door to disengage it from the gears. You'll have to support the window glass once the motor is disengaged.

Remove the motor from the door.

Installation is the reverse of removal. To avoid rusting in the drilled areas, prime and paint the exposed metal, or, cover the holes with waterproof body tape. Torque the motor mounting bolts to 50-85 inch lbs. (6-10 Nm). Make sure that the motor works properly before installing the trim panel.

Thanks for the advise and tips. I will let you know what I find. My pickup is at my remote shop and I should get back to it this weekend.

Thanks again.

PS: It took a little time to get back into my "shop". Know knowing exactly what the problem was and not wanting to work partially in the blind, I opted to drill the blind rivets and remove the entire assembly. Repair was then easy and reassembly with short 1/4 bolts and lock nuts was easy.

Thanks for advice on both approaches. Now that I have the experience, the next time I will drill the door panel and just remove the motor.

Thanks again. And I will donate!
