Volkswagen Passat Window Motor
Signs that Your Volkswagen Passat Window Motor is Failing
The automated feature of your car's power window comes from the Volkswagen Passat window motor. It is powered electronically for you to be able to open and close the window at the touch of a button. However, if one of the windows in your car is moving slower than usual or is not moving at all, then maybe there is something wrong with the motor. Diagnose the symptoms you observe by following these tips.
One window moves slowly
If one window is working but is moving very slowly, then the window motor might be failing.
To diagnose this symptom, check for proper voltage at the power window motor plug while the switch is depressed.
One window does not work
If one of the car's windows fails to move when you press the switch to lower it, the most likely cause would be a bad motor.
To confirm this fault, you will need a voltmeter. First, check for voltage at the switch when the ignition is on. If the switch is receiving voltage, but the door motor is not doing anything when the switch is pressed, then the problem could be a bad window motor or a bad switch. Use a fused jumper wire to bypass the switch and route power directly to the motor. If the component is still not doing anything despite having a direct connection to electric power, then it has failed and needs replacing.
Other troubleshooting tips
Aside from the above, you may also want to take precautionary measures by doing the following:
- Find out if there is an electrical problem by following along the wires on the window motor to see if everything is connected. Check for damaged wires as well, and inspect the fasteners to make sure that they are all tight.
- Look over the window gasket-the rubber strip around the frame of the window-to make sure it is sealed properly. Run a flat-head screwdriver through the gasket and clean out anything that may be in the window's way. Make sure that the gasket is not loose or torn; if there are any tears, apply super glue to stick them back together.
