Power Widow Not Working

Repairing an Electric Car Window

Electric window mechanisms are one of the most common parts of a car that breaks over time, especially the driver’s window, which is generally used more than the rest. If your driver’s window (or any electric window in your car) stops working, it’s not a big worry, and it can usually be repaired.

First, identify the problem.

There are several systems that work together to open and close your windows, including the electrical circuit, the motor, the connection to the window, and the guides that keep it in place.

Is it just one window that isn’t working, or have all of your windows stopped working? If all windows stopped working, you might have an issue with the main wiring circuit.

If, when you try to operate the window, you can hear the mechanism working, but the window doesn’t move, the issue might be with the mechanical links between the motor and the window.

If your window moves, but only very slowly, it jerks around as it moves, or it gets stuck partway, the issue may be with the motor or with the guides that keep the window in place as it moves.

Next, check for the root of the problem.

The fuse – If you suspect an electrical issue, which usually affects all windows, first check the fuse connected to the window system. Check your manual to see where the fuse is located, and determine whether it needs to be replaced.

The power supply – The windows are usually powered directly by the battery when the ignition is on. Checking the power supply requires the right tools, so if you aren’t experienced with electrical systems, you may want to ask a professional.

The electrical faults – If you know that the power supply is okay, it’s time to remove the door panel so you can access the window mechanism. Check the wiring and switches connected to the motor for power. Again, if you aren’t experienced, it’s important to consult a professional. If you can tell the motor is running, however, electricity is moving through the circuit.

The window motor – Once you’ve determined that the issue isn’t electrical; it’s time to look at the motor. You can access it by removing the inner door panel. First check for obvious damage, like wires stuck in the wrong place or damage from an accident. Sometimes, lubrication can help. Test the motor before replacing the door panel.
