If you drive around Pasadena in a car built within the last few decades, chances are that you have the luxury of power windows. But while power windows allow you to do things like open and close all of your windows just by lifting a finger, they come with one fatal flaw: like pretty much all things electrical, they will eventually fail. And when they fail, whether they are stuck rolled all the way up or completely open, it can be either a minor inconvenience or a major headache.
Some symptoms of a problem with your power window system include abnormal noises, windows that move slowly, windows that only work sometimes, or no longer move at all.
To find out what is causing a power window failure, technicians may have to check every component, from the switch to the motor and wiring. They may use a wiring diagram and electronic testing equipment to identify the fault. Once the faulty component is figured out, it can be replaced. However, sometimes replacing one part will trigger another one to fail, and the diagnostic process will have to be repeated.
Power window switches are located inside of your vehicle, usually on each door. They function by taking input and sending power to the window motor, opening or closing the window. Power windows may fail for a number of reasons, not only a malfunctioning switch. It could also be a problem with the window motor, fuse, or regulator.
Because the power window system is a closed system, it is usually not inspected during regular maintenance visits. If you notice any problems with your power windows, you should schedule an inspection. Power window systems usually last for a long time, but using them excessively and unnecessarily can shorten their lifespan.
