If you have more experience with car repairs and the right tools, you can troubleshoot automatic window repair. Keep in mind that you will have to disassemble your door panel, making sure you know how to put it back on correctly.
Problems that require power window repair are a broken motor, damaged switches, or regulator assembly issues. To pin the problem, you will have to diagnose it. For doing so, a test light is a great and handy tool. Start by testing if the switch is getting power. If there isn’t, chances are this is due to a broken cable or a blown-out fuze.
If you have ensured the switch is receiving power, test the window motor next to see if the power is going to it with the test light by turning the switch on and off. If there is, and you can still hear the motor working by switching the window up and down, chances are the problem is the regulator.
