Our 1969–1972 Corvette Windshield Wiper Door Vacuum Switch is an exact reproduction of the original part, ensuring a factory-correct replacement for your C3 Corvette. The vacuum switch plays a crucial role in the wiper door operation, preventing damage to the wiper arms and ensuring the door closes properly when the wiper arms are parked.
If your original wiper control valve is failing and causing a vacuum leak, replace it with our high-quality reproduction. The switch is located under the passenger-side wiper arm—simply check the base of the arm, and you'll find it there. When the wiper switch is turned off, the wiper arms move to the park position and activate this switch. This starts the process of lowering the wiper door, activating another switch on the firewall, and ensuring that the wiper door closes without damaging the wiper arms. The engineering nightmare of proper wiper door function has been solved!
