What is a window motor regulator?
Most modern vehicles use power windows—and a window motor/regulator assembly helps you open and close those windows with the press of a button.
When you push your vehicle’s power window switch, the electric motor will activate and help the regulator move your window up or down. A regulator will also keep the window properly aligned as it moves.
When should I replace the window motor regulator on my car?
You might notice the following signs if it’s time to replace your window motor/regulator assembly:
Window won’t open or close: If your power window will no longer open or close, it could be due to a number of issues, such as a faulty switch, electrical connector, or a failing motor or regulator.
Strange noises: Noises like grinding, squealing, or clicking when using your power windows could all be signs of a failing window motor or window regulator.
Window glass is crooked: The window regulator helps keep your window properly aligned in your vehicle’s door—so if it starts to look crooked, a bad regulator could be the culprit.
Window won’t stay rolled up: If your window slides down on its own, a failing window regulator could be the culprit.
How often should a window motor regulator be replaced?
You’ll only need to replace your window motor/regulator assembly if it stops working. In some cases, the assembly can last for the life of a vehicle—but just like any part, they can be subject to early failure.
Can I replace my window motor regulator myself?
Replacing a window motor/regulator assembly can be a pretty straightforward job—but you’ll need to exercise some caution so you don’t accidentally damage your window or other parts.
