Chevrolet C1500 windshield wiper failure due to faulty wiper motor control board replacement on Chevrolet C1500

Some Chevrolet C1500 owners report experiencing windshield wiper failure due to a faulty wiper motor control board. This issue can manifest as wipers that do not park properly or fail to activate when the switch is engaged. Troubleshooting may involve accessing the pulse circuit board to check for bad solder connections and testing the voltage at the motor to identify potential problems like blown fuses or malfunctioning relays. Owners may need to unplug the harness connector and remove the motor cover for inspection and repair. To resolve the issue, replacing the faulty wiper motor control board with the correct part number is recommended. Additionally, regular maintenance and prompt attention to loose connections can help prevent future failures.
