What’re Common Reasons Caused the Power Windows Not Working?


Reason #4: The Power Windows sticking in the tracks

When you find that the power windows not working properly, but occasionally get stuck in motion. You may need to press the power window button several times to get the window to “unstick” and move all the way to the closed or open position.

This is where the window glass itself is getting caught on the edge of the track.

In this case, you will want to lubricate the window track so that the window glass slides up and down smoothly.


Reason #3:Blown fuse or blown motor

You may need a circuit tester firstly, recommend getting a SigmaProbe circuit tester, a powerful tool and easy to use for activation & check the electrical system problem.

When you use the SigmaProbe circuit tester to activate a faulty window, what do you hear when you press the switch? If you hear a whirring or clicking sound, you know that power is going to the motor. But what if you don’t hear anything? That tells us that you have an electrical problem.

If the fuse associated with your power windows has blown, you may need to install a new one and use SigmaProbe circuit tester to check the entire system for problems. Or, the motor in the door itself may have blown, then you need to have the motor replaced.


Reason #2:Faulty window switch

If the power windows switch itself stops working, and the windows still don’t respond to the switch even though power is going to the window motor and the window motor is in good condition, the switch itself may be bad.

One way to figure out if the switch is bad is to try cranking up the window in another way – for example, if you suspect the power window not working on the passenger-side caused by the window switch is bad, try the driver-side switch and crank down the passenger-side window. If it works, you know the passenger-side switch is the problem.


Reason #1:Window regulator failure

The window regulator is the metal arm that connects the window glass to the window motor, both of which are located inside your car door.

After working for a long time, the window regulator can fail in various ways.  It may be disconnected from the motor, or from the window glass itself. Recommend use the Sigmaprobe circuit tester to check it as well.
