What is the Power Window Switch all about?
The power window switches are located 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 not move up or down is a fuse, window regulator, or window motor failure.
Keep in mind:
If the power window switch is not controlling the windows, it may not be a malfunctioning switch. Instead, it could be a problem with the window motor, fuse, or regulator.
How it's done:
- Remove and replace 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 inspected during regular maintenance or service. As soon as you notice that one of the power window switches isn’t working, or is behaving abnormally, you should schedule an inspection. Power window switches normally have a long lifespan, but you should avoid using them excessively and unnecessarily; playing with the switch can shorten the lifespan of the system.
What common symptoms indicate you may need to replace the Power Window Switch?
- Window will not roll up or down.
- Abnormal noise when you try to move the window up or down.
- Window operation is intermittent.
How important is 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 malfunctions, 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.
