How to Replace a Window Motor on a 1985 Ford F250

The 1985 Ford F250 power windows move up and down thanks to the efforts of the power-window motor. When you push the window switch, it closes the power-window circuit. This energizes the window motor, which then turns a gear in the motor's nose. That gear turns another gear on the window regulator, which moves the window glass. If the motor short-circuits or locks up, the entire system comes to a halt until you replace the motor. If you have basic auto-repair experience and an hour of free time, you can replace the window motor in your 1985 F-250.

Tools Used: Trim tool, Phillips screwdriver, Packing tape, Socket set

Shove the F-250's window to the top of the window frame by hand. Tape the window to the top of the door with packing tape.
