Power car windows, while a convenience standard on many modern cars, can instill panic in a car owner when they fail to operate properly. Although power windows are relatively simple mechanisms, there are three main points of failure that may cause the window to cease operation. The faulty component may be diagnosed, and even repaired, with only minimal inconvenience.

Fuse

Perhaps the easiest power window fault to diagnose and repair, the fuse is the small link between the power window and the car’s main electrical circuitry. If there is a power issue within the power window circuit, the fuse will blow, stopping the flow of electricity to the power windows and preventing potential damage.
