One Window Inoperative

The window glass and regulator mechanism must be free to slide up and down for the power window motor to function properly. If the window glass and regulator is not free to move up and down, the motor will overload and trip the integral circuit breaker. To determine if the window glass and regulator are free, disconnect the regulator plate from the glass. Then slide the window up and down by hand.

There is an alternate method to check if the window glass and regulator mechanism is free. Position the glass between the up and down stops. Then, shake the glass in the door. Check that the glass can be moved slightly from side to side, front to rear, and up and down. Then check that the glass is not bound tight in the tracks.

If the window glass and regulator mechanism is free, refer to DOOR MODULE  . If the glass is not free, inspect the window glass mounting and operating hardware for damage or improperly installed components. Refer to DOORS - FRONT or DOORS - REAR article to check for proper installation or damage of the window glass mounting and operating hardware.
