Restore dependable operation of your Corvette's vacuum-operated headlight and windshield wiper door system with this 1968-1982 Chevrolet Corvette Headlight & Wiper Vacuum Actuator Relay Valve. Designed as a direct replacement for the factory vacuum relay valve, this precision-engineered component directs engine vacuum to the headlight actuators, allowing the concealed headlights to open and close properly. On 1968-1972 Corvettes, this same relay valve is also used for the vacuum-operated windshield wiper door system. Over time, the original relay valve can develop internal leaks, sticking diaphragms, or worn seals, resulting in slow-moving, partially opening, or inoperative headlight and wiper doors. Replacing the relay valve restores proper vacuum control and reliable system performance.
Manufactured to meet or exceed OEM specifications, this restoration-quality relay valve is engineered for an accurate fit using the factory mounting locations and vacuum hose connections. The valve features factory-style ports and durable internal components for long-lasting performance and dependable vacuum control. Whether you're diagnosing a faulty vacuum system, replacing a leaking original relay, or completing a concours-quality restoration, this actuator relay valve delivers the factory-style fit, function, and reliability Corvette enthusiasts expect.
