The window motor is not always the reason why a power window stops functioning. Before jumping the gun and purchasing a replacement motor, it is important to first check if it is indeed the problem. The following table lists some of the things that one should first check before replacing the window motor.
Bondo : F 550
I have a 05 F550 and it took me 15 minutes! Only had to remove the three screws holding the window motor, and these were accessible through holes in door. Remove the screws, motor falls out, unplug and plug in new motor, reach up and hold it in place, replace the three screws and done! Took longer to find the screws (2) to hold the door panel on. One under the switch panel, other behind the red plastic panel, lift door trim up and off.
If you are looking for a replacement window motor, you can purchase one on eBay. Begin by typing in the name of the product that you are looking for in the Search bar. Better yet, start from the page and key in the year, make, and model of the vehicle. This helps ensure that the motor you purchase is compatible with your car. After the initial search, you can also use the filter options on the sidebar to help narrow down the search results.
