The power window switch makes it easy to open and close the windows in your vehicle. The switches are located near each window, with a master panel on or near the driver’s door. Over time, the fuse, motor, or regulator can go bad and need to be replaced. If you suspect your power window switch is going bad or failing, watch for the following symptoms:
1. All the windows quit working
If all of the windows quit working at once, meaning there is no response when you push the power window switch, chances are there is a loss of power in the electrical system. Normally, a bad relay or blown fuse is the cause of this problem. The drivers master switch may also be the cause.
2. Only one window stops working
If only one window stops working, the problem could be a bad relay, fuse issue, bad motor, or the power window switch has failed. The most common reason for one window to stop working is the switch, so this should be looked at by a professional mechanic to have your power window switch replaced. Once the mechanics replace the switch, they will test the windows to make sure the rest of the system is working properly.
3. Window works from master switch only
In some cases the window may not work from its own switch, but the master switch can still put the window up or down. In this case there is a good chance that the power window switch has failed and that the other window components are working properly.
4. Windows work sometimes
When you open a window fine, but it doesn’t seem to close properly, this could be a window power switch issue. The opposite could be true as well, the window would close fine, but does not open like normal. The switch could be dying, but has not fully gone out yet. There is still time to replace the power window switch before your window gets stuck open or closed. Have your vehicle serviced as soon as possible because in case of an emergency situation, you may need to open and close your windows fast.
