What do I do when my automobile power window starts running slowly?

Is your power window running slow? Does it take longer than 8 seconds to get from the bottom to the top or does it stop in the middle when you are trying to roll it up? This could be the first indication that your power window motor is burning out and getting ready to die. When this happens the window will go down just fine and without trouble. Remember, on the way down, the regulator has the weight of the glass on it’s back and gravity on it’s side, so it won’t need the power of the motor to lower the glass. It’s on the upstroke where the window motor is really load tested and you’ll have trouble.

You may think that helping the glass along by lifting the glass and operating the window at the same time will help you get the most out of that motor, but you run the risk of breaking the regulator or glass carriers every time you put your hand on that glass and that would just mean more money out the window!

Power Window Repair recommends that you get the window up and leave it up until it can be repaired. A failing power window motor will draw more power through the power window switch and can cause additional problems there.

What is a Power Window Motor?

Also called a window lift motor, or automobile glass lift motor, the power window motor is the electrical motor that when attached to the power window regulator, raises the window glass up and down.

The electrical connection is carried via the power window switch, which when depressed or raised creates an actuation telling the window motor whether to move forward or backward. As the motor gear moves forward and backward, the regulator gear or cable spool wheel is also moved.

Symptoms of power window failure include slowing over time. Anything over than 7 seconds from top to bottom should be of concern, especially in a newer vehicle. The motor may also stop in the middle of travel on the way up and then after a period of time, may continue to the top of travel. Motors rarely have difficulty on the way down, as they have gravity on their side and the weight of the glass on their backs. It’s on the way up where a motors true strength is tested.

Noise is rarely associated with window motor failure with the exception of those with inherent inner gear issues such as Nissan and Mazda. In those vehicles, a crunching noise will be present similar to a failing regulator, however it is indeed the motor that’s causing your problem.
