What does a power window switch do?
A power window switch sends the signal that drives the window motor up or down. This is a single-button switch used at the front-right position (paired with the driver's master switch) or at either rear position. Over time, the internal contacts can wear, causing the switch to stick, feel spongy, or stop responding.
What are the symptoms of a failed power window switch?
A worn switch may cause:
- A window that doesn't respond to the switch
- A switch that feels sticky or requires extra pressure
- Intermittent window operation
- A window that only works from a different switch location
These symptoms can also come from a failed window motor/regulator or wiring fault. Testing the switch itself will help isolate the cause.
