When traveling, it’s easy to get comfortable in the car. You can get air and get warm with just a press of the switch. But the power window switch can stop working without you knowing.
Luckily, the repair is straightforward.
In this article, A Plus will provide an easy-to-follow guide on how you can repair your car power window switch. All you need to do is follow the guide below.
Tools Needed
- Screwdriver
- Flat-Tipped Screwdriver
- Multimeter or Voltmeter/Ohmmeter
Identify The Problem
Check for blown fuses in the fuse box. It’s often under the dashboard, close to the steering wheel. Check for any loose wires in the fuse box, and replace any blown fuses as necessary. Check to see if the windows are working after repairing the loose wiring.
A non-functioning switch may be the issue if only one side of the window is not working. Additionally, there could be an issue with the window’s motor or wiring from the switch to the motor. Power window malfunctions can occur for a variety of causes. It’s crucial to thoroughly examine all parts of the device to pinpoint what is wrong.
Inspect the Switch
Typically, the power window on the passenger side is not wired to the driver’s side. Each power window has wiring that runs from the switch to the motor in that specific window. If the passenger windows are malfunctioning, it may be a problem with the switch on the passenger windows, the driver’s side, or both.
Remove the Switch
Each of the window switches has a total of four tabs. Release each of these four tabs to remove the switch. It’s important to note that these tabs are delicate and brittle. Use a flat-tipped screwdriver under two tabs, then release them quickly. In some cars, you might need to remove the panel.
Ensure the Switch is Working
Use the multimeter to inspect the switch contacts. The switches’ high resistance may be the result of dirt. If this is the case, the problem can be fixed by simply cleaning the contacts. Reinstall the switch on the assembly by re-inserting the tabs after cleaning the contacts.
Check the Switch Again
Check again to verify if the switch is operating normally after being reinstalled. If the windows start to function again, you generally don’t need to do anything further.
