C3 1968-1982 Corvette Headlight & Wiper Vacuum Door Open Switch (Under Dash)

Restore manual control of your Corvette's vacuum-operated headlight and windshield wiper door system with this 1968-1982 Chevrolet Corvette Headlight & Wiper Vacuum Door Open Switch - Underdash. Designed as a direct replacement for the factory underdash override switch, this component allows you to manually open the vacuum-operated headlight doors and, on 1968-1972 models, the vacuum-operated windshield wiper door for service, maintenance, or emergency operation. Over time, the original vacuum switch can wear internally, develop vacuum leaks, or fail to operate properly, resulting in inconsistent or inoperative headlight and wiper door functions. Replacing the switch restores dependable manual control while maintaining the original operation of your Corvette's vacuum system.

Manufactured to meet or exceed OEM specifications, this restoration-quality underdash vacuum switch is engineered for an accurate fit and reliable performance. It installs in the factory underdash location and connects directly to the original vacuum hose system without modification. Constructed from durable automotive-grade materials, the switch provides long-lasting operation and dependable vacuum control. Whether you're troubleshooting the vacuum system, replacing a leaking original switch, or completing a concours-quality restoration, this component delivers the factory-style fit, function, and reliability Corvette enthusiasts expect.
