Power windows offer effortless operation and convenience. However, in order to operate, each window needs a regulator and a motor – this is called the power window motor and regulator assembly. Generally, they’re made as a single unit (separate components joined in a single footprint). Which means that if either the motor or the regulator fails, you’ll have to replace them both. Of course, this is by no means true for all makes and models out there. Some vehicles have separate units and you can replace only the failed component.
When should I replace my Power Window Motor and Regulator Assembly?
You’ll find that a power window motor and regulator assembly replacement is necessary in several different instances. If your regulator begins to fail, your window will not go up or down evenly, or you’ll only be able to move it with your hand (pushing the button drops the glass into the door). If the motor fails, you won’t be able to move the glass at all. If you’re experiencing problems with your windows, a discount power window motor and regulator assembly will get things back in working order.
What happens if I don’t?
If you decide against a power window motor and regulator assembly replacement, you’ll face some serious problems depending on what has failed. If the regulator itself has failed, you may not be able to roll your window up at all. If the motor has failed, you won’t be able to let it up or down.
