GMC Window Motor

The power window is an often ignored but very important part of any vehicle. This is the feature that allows you to roll down and up your window with just a push of a button.

Before the power window was introduced in the early 40’s, the window was equipped with a manual window where you have to crank the handle to roll down the window. Pressing the window switch sends an electric current to the window motor that will move the window up or down, whatever the direction is. The lifting mechanism is the heart of the power window system. It uses a very neat linkage to lift the window glass while maintaining its level. The GMC Window Motor is attached to a worm gear and some spur gears to produce a large gear reduction to produce enough torque to move the window. The gears have a self-locking system so you cannot force the power window open. This makes it very important to choose the correct window switch especially for those with children aboard.

We all know that children love to play inside the car by putting their head out of the window, obstructing the progress of the window glass. If the GMC Window Motor is working perfectly, this maybe a problem because the window glass will automatically go up even with obstructions. But, when you find your power window is failing, you might want to test if your window motor is working. Moisture can cause the motor to corrode.
