What is a window motor?
A vehicle’s power window motor powers the mechanism that allows you to open and close your windows with the touch of a button.
Different vehicles may have slightly different mechanisms in place, but generally, your power window switch will activate an electric motor, which will power the regulator to move your window up or down.
When should I replace the window motor on my car?
The following symptoms can all point to power window motor problems:
Power window won’t work at all: If your door window doesn’t move an inch when you press your window switch’s buttons, it’s possible the motor may not be functioning properly.
Window rolls down more slowly: If one of your power windows is rolling down more slowly than it used to, a worn or failing window motor could be a possible culprit.
Grinding or squeaking sounds: If your window makes grinding or squeaking noises, it’s possible your window motor could be on its way out.
How often should a window motor be replaced?
Window motors can certainly last the life of your vehicle, but just like any other car part, they can also fail prematurely. When window motors stop working, it’s often due to excess wear, electrical problems, or a buildup of excess dirt and debris.
If your window motor fails early, you’ll need to replace it to use your vehicle’s power window again.
Can I replace my window motor myself?
With the right tools, many drivers are capable of replacing a power window motor themselves—but it’s a job that should be done carefully since wrong steps could lead to a shattered window glass or other damaged parts.
Of course, some assemblies can be more complicated than others—if you don’t feel comfortable replacing a window motor yourself, a certified mechanic can do so for you.
