How do I know if my window lifter switch is bad?
- By:Icelandic Trade
A window lifter switch is an electrical component that controls the movement of a power window in a vehicle. If the switch is not working correctly, it can cause issues with the window movement, including not opening or closing the window or making strange noises. Here are some signs that your window lifter switch may be bad:
1. Window won't open or close: If you press the window lifter switch, and the window does not respond by opening or closing, it could be an indication of a bad switch.
2. Window opens or closes slowly: If the window moves slowly, even though the switch is pressed all the way down, it could be an indication of a bad switch or a motor that is going bad.
3. Window opens or closes intermittently: If the window works sometimes, but not all the time, it could be an indication of a bad switch or a loose connection.
4. Strange noises: If you hear strange noises coming from the window when you try to open or close it, it could be an indication of a bad switch or a motor that is going bad.
5. Other power functions not working: If other power functions in your vehicle are not working correctly, such as the power mirrors or power seats, it could be an indication of an electrical issue with the vehicle, which could also be affecting the window lifter switch.
If you are experiencing any of these symptoms, it is recommended to have the window lifter switch checked by a professional mechanic or auto electrician. They can diagnose the issue and determine whether the switch needs to be repaired or replaced.
