Chevrolet K2500 Mirror Switch
Culprits behind the Common Problems of the Chevrolet K2500 Mirror Switch
Powered mirrors make life easier, especially that you can adjust them without sticking your hand outside the window-all you have to do is press on the mirror switch. But over time, you will experience a power mirror that doesn't respond to the switch. Yes, your Chevrolet K2500 mirror switch can go bad. So learning the common culprits behind these problems is a great idea. Take note of these troubleshooting tips:
Having bad contacts is one of the reasons why your mirror won't work when you use the mirror switch. In this case, you need to remove the switch panel from the door and make sure to disconnect all plugs or wires that are attached. This is needed so you can access the contacts inside the mirror switch. Using screwdrivers to pry the cover should work, but be careful not to break the switch housing. And once you have opened the switch, look for your contacts and clean them using a cotton swab, carburetor cleaner, and sandpapers cut into small pieces. Cleaning your switch's contacts should make your mirror switch work again. Keep in mind also that you should only blame the contacts if the fuses are good and that enough power is supplied.
If your mirror doesn't move, you should first check if the mirror switch is working properly. To do this, you need to disconnect all wires from your switch and connect to them the leads of the multimeter instead. This should tell whether the mirror switch is faulty or not. If the multimeter reads 12 volts or higher, then the switch is fine. Otherwise, you have to buy a new mirror switch to replace the faulty one. Remember, though, that you may have to put your key on in the ignition when you test your switch.
In the event the mirror still doesn't respond to the switch, although the multimeter test shows that the switch is in good condition, you will need to check your fuse box for a blown fuse. If you don't know where your car's fuse box is, you can refer to your car manual to find its location. Should the fuse is blown out or melted, remove it and install a new one. Replacing the bad fuse should easily solve this problem.
