Keeping your 1968-1982 Headlamps and Wiper Door in working condition is a must. This Vacuum Relay is a main reason of failures or improper operation of your Headlight Bucket or 1968-1972 Wiper Door systems. Replace your faulty units with our high quality reproduction Headlamp & Wiper Door Vacuum Actuator Relay. This item is no longer offered by GM and is only offered as a reproduction. As of this listing we know of two manufacturers for these valves. One is very cheaply made and the other that we carry meets or exceeds factory specifications and has been in production for over 20 years. A simple way to tell them apart is the metal air tube connection will be beveled on the higher end valve but on the lower end valve it will be just a straight unfinished cut. The Headlight Actuator Relay installs in between the headlight assemblies and controls the vacuum circuits to extend or retract the headlight actuator to open or close the headlights. This Vacuum Relay Valve serves the same purpose to control the operation of the 1968-1972 Windshield Wiper Door. Please see our other listings if you are in need of just one valve. This listing is for two C3 Headlight Relays for use on both the left and right headlights or one headlight and the windshield wiper door. 1968-1969 used just one relay for the headlights in center of nose near the hood along with one for the wipers located on right fender. 1970-1972 used 2 relays for headlights and one on firewall or fender well for the wiper door. 1973-1982 used a total of 2 relays for the headlights as the windshield wiper door was no longer an option.

Frequently Asked Questions
Q: What vehicles are compatible with the C3 Headlight Vacuum Actuator Relay Valves?A: These relay valves are designed to fit all C3 Corvettes manufactured between 1968 and 1982, ensuring compatibility with your vehicle's headlight and wiper door systems.
Q: How do I know if my current headlight vacuum actuators need replacement?A: If you are experiencing issues with your headlamps not extending or retracting properly, or if the wiper door is not functioning, it is likely that the vacuum actuators are faulty and should be replaced.
Q: What is the difference between the high-quality reproduction and cheaper alternatives?A: The high-quality reproduction valves we offer meet or exceed factory specifications and feature a beveled metal air tube connection, while lower-quality valves have a straight, unfinished cut, which can lead to premature failure.
Q: Can I use these vacuum relays for both headlights and the wiper door?A: Yes, this listing includes two vacuum relays, which can be used for either both left and right headlights or one headlight and the windshield wiper door, depending on your vehicle's configuration.
Q: What should I do if I only need one relay instead of the two included in this listing?A: If you only require a single vacuum relay, please check our other listings where we offer individual units specifically for customers who need just one replacement.
