COMFORT / INTERIOR AUTO PARTS: WINDOW WINDER SWITCH
HOW TO DETECT THE POWER WINDOW BUTTON FAILURE
As a start, you need to switch on the ignition and press the power window button. You should hear peculiar clicks. Then you have to remove the panel on which the part is situated and try to close the corresponding contacts. Depending on what button position is simulated, the window should either lower or raise. If the window raiser operates, the button requires replacement.
If you have a multimeter, set it to the continuity test mode and connect one of the probes to the corresponding terminal on the button. Attach the second probe to the vehicle body. When you push the button, you will hear a sound if it is serviceable. You should see the wiring connection diagram in your car technical documents.
