The window motor in the Ford F250 is responsible for creating the torque that runs the window up and down at the touch of a button. The motor actuates a scissor like mechanism called a regulator, which actually moves the window. If your window motor fails, your F250 will need a new one before the window will work again. Before you decide the window motor itself is the source of the problem, try replacing the fuse or the switch.
Remove the fasteners from the door panel with the socket set. In the Lariat and King Ranch packages, you may need to remove some trim covers by carefully prying them off with the pocket screwdriver in order to access the fasteners.
Use the trim pin removal tool to unseat the trim pins holding the door panel to the door. It is easiest to begin at the bottom of the door panel, at the rear edge, and move your way forward, popping each trim pin out as you go. You can buy a trim pin removal tool at the auto parts store for around $10. Once all the trim pins are unseated, lift the door panel up and away from the door a few inches before moving to the next step.
Disconnect the wiring harness connectors of the power window switch and power lock switch. Reach your arm between the door panel and door to access the harness connectors. You may need the pocket screwdriver to unseat the connectors from the switches.
Set the door panel aside and peel back any water barrier. The water barrier is essentially a sheet of clear plastic glued to the door. Do not completely remove it, but peel it back far enough to give you access to the door's interior and the window motor.
Locate the window motor and use the socket set to unbolt it from the window regulator. You may need to move the window glass up or down to access it. In some cases, depending on your model year, the window motor may be riveted to the regulator. If so, you will need to drill out the rivets. Once the motor is free, disconnect it from the wiring harness in the same manner you disconnected the window switch. Remove the motor from the door.
Position the new motor and use the fasteners (if the old one was riveted in, the new motor should come with fasteners) and socket set to bolt it in place. Connect the wiring harness to the motor when done.
Reinstall the door panel by reversing the steps you used to remove it. Don't forget to put the water seal back in place and reconnect the switches. You can reseat the trim pins with a firm hit from the side of your fist on the door panel on the opposite side of the pin's location.
