You may not notice it much, but your SUV's power window feature is a very convenient way of controlling your vehicle. Through this, you can close or open all of your windows with just a flick of a switch. This is all thanks to your window motor, an electrical component located in each of your doors. This part is prone to various problems that can make it stop from working. When you encounter these, you should be aware that your window motor is the first place to look at. Following are some signs that tell you to check your Jeep Grand Cherokee window motor.
When you smell something burning in your cabin while you are pressing your window switch, one window motor is surely toasted. This happens when this electrical component carries too much load. This is most likely to happen when there is an obstruction on your window glass, making the motor work harder than it should. Also, it may be caused by a sticking window switch that keeps on telling the window motor to work even though the window is closed or opened already.
This happens when your power window motor is not working well to the point where the relay is delivering more voltage to it. This setup affects the dashboard and interior lights. If you see these lights flicker or dim while trying to activate your power window, your window motor may be damaged.
When you hear humming or grinding noise inside your door panel, your Jeep Grand Cherokee window motor is starting to fail. The internal gears and parts of the motor gets rusted over time especially when water and moisture make their way into the part. This can cause your window motor to work noisily. This sound eventually leads to total motor failure. When this happens, you should replace the motor for smoother window operations.
If your window is moving sluggishly, there may be an issue with either your window regulator or window motor. When you experience this, check your window regulator first. You can do this by taking out the door panel. If the window regulator is intact and good, you may suspect a bad window motor. This can be a sign that the motor is at the end of its lifespan.
