What to know about the Power Window Switch:
The power window controls are found inside the car, usually on each door. This switch takes input from either the driver or other passengers, and sends power to the window motor, which opens or closes the window. The common reason for the window to be stationary is a fuse, window regulator, or window motor failure.
Facts to Note:
If the power window switch is not controlling the windows, it may not be a spoilt switch. Rather, it could be a malfunctioning of the window motor, fuse, or regulator.
How to Fix:
Remove and change the power window switch.

Inspect window motor, wiring, connectors, power source, and fuses.
Check for proper operation of windows.
The power window system is a closed system, so it will not be checked during normal maintenance or service. As soon as you notice that one of the power window switches is notfunctioning, or is behaving abnormally, you should schedule an inspection. Power window switches usually have a long lifespan, but you should avoid using them excessively and unnecessarily; playing with the switch can shorten the lifespan of the system.
Common symptoms indicating you may need to change the Power Window Switch:
Window will not roll up or down i.e becomes stationary
Abnormal noise when you try to move the window up or down.
Window operation is intermittent.
Importance of this service:
Power window systems allow you to roll down and roll up the windows in a modern vehicle. When you press the window buttons located on the inside of the doors (or sometimes on the center console), the switch triggers the power window motor, which rolls the windows up or down. When the power window switch becomes abnormal, there’s no communication between the window buttons and the power window motor, and you’ll be unable to roll up or down the window.
