Power windows not working in a car can be caused by several things. Checking for power to the window's motor normally requires removing the door panel to access the wiring. After access to the power window wiring is gained, a test light or meter can be used to see if it is getting power and ground. If a slight flicker or dimming of the interior lights occur, this indicates that the;switch is functional and the motor is bad. The;motor will be heard when pushing the;switch in many cases but the window won't work correctly due to the failed;regulator.
- Sometimes;electric contacts in the window switch can be worn, corroded or dirty.
- After accessing the;motor, try tapping on it;with an object; (like a small wrench or a 3/8" extension);- if it temporarily works, the window motor will need to be replaced.
