Power Windows not Working - Problems

If there is a malfunction of windows on both sides, the very first possibility can be a defunct fuse. Note that if only one window is not working, then the problem is somewhere else, and not the fuse. Here the problem can even be a faulty switch, wiring disconnection, or a bad motor. If both windows do not seem to work at all, the problem can even be in the relay. In case the windows are moving too slow, you will need to get the window tracks lubricated for smooth operation. The window mechanism may be misaligned due to constant friction with the glass. The following consists of some troubleshooting steps for power windows.

Power Windows not Working - Troubleshooting

For accessing the power window electrical setup, you will have to take out the inner door panels. In order to check if the problem is on the fuse; turn the ignition on but not the engine, and press the window button. If there is a bad fuse, there will not be any movement in the windows. If the fuse is good, there will be some movement; even just a quiver of the window. If you are certain that the fuse is bad, you will have to open the fuse box and reset the fuse.

Check the wiring of the complete system if any wire has come loose or been disconnected. You can use electrical tape to secure wire connections. You can even opt to replace the power window switches. Poor power window performance may be due to dirty and worn out switches. Remove the block which houses the switch, remove the old switches, clean the block, and install new switches. Another troubleshooting step is to remove the jumper terminals and relay, and get the jumper replaced.

Use a test light to make sure of proper connections to the motor. If all connections are fine, you will need to get the window motor replaced. Loosen the bolts that secure the motor to the door panel, and replace it with a new one. Use a multi-meter to check if the new one works fine, and reinstall the door panel back. Window motors are available at just about $50 at any car parts store. Another possibility of the problem of the car window not being on track is a bad regulator. In this case, you will hear the motor running, but the window will not work as expected. Here, you will have to get the regulator replaced.

These are some of the basic tips that can be used for diagnosing problems related to power windows not working. Note that if you are not sure about the technicalities of the power window setup, it is better to take the automobile directly to the car repair shop or the showroom. Diagnosing the actual problems will surely help you reduce repair costs to be spent on auto mechanic services.
