How to Replace a 2002 Silverado Windshield Wiper Motor

The Silverado's wiper motor drives the windshield wipers on the truck. The 2002 Silverado uses a canister-type wiper motor mounted on the firewall in the engine bay. When the wiper motor starts to fail, the wipers may hesitate before failing completely. If you notice any squealing, the motor needs to be replaced. If your motor fails during a rainstorm, you could end up in a serious accident. Replacement wiper motors can be purchased from most auto-parts stores.

Things You'll Need

• Phillips-head screwdriver

Instructions

1. Open the hood of your Silverado and unplug the electrical connector running to the bottom of the wiper motor, which is mounted on the firewall.

2. Unscrew the screws holding the wiper motor to the firewall and slide the wiper motor off the wiper linkage.

3. Slide the new motor into place and secure it to the firewall using the factory mounting screws and a screwdriver.

4. Reconnect the power connector to the bottom of the wiper motor.
