How to Repair a 1990 Ford F150 Power Window Motor
While Ford does not offer repair parts for the 1990 F150 window motor, you can replace the motor itself with far less effort. The window motor transforms electrical energy from the power window circuit to kinetic energy it uses to move the window regulator gear. The regulator then moves the window itself. Because electric motors can short circuit or seize internally, you can expect to replace one or more of them in the first 200,000 miles of service. Anyone with good auto-repair abilities can perform this repair.

Slide the tip of the trim tool between the lower, trailing edge of the door panel and the door skin. Pry the door panel off the door at that point, then work your way around the door panel's perimeter to pry it completely off the door.
