Fits all C3 1968-1982 Corvettes. This item includes 2 headlight or wiper vacuum cleaner relay actuators. This item offers the best reproduction quality. All metals in this unit are corrosion resistant. This listing is for 2 vacuum relays. If you only need one, please see our other listings.

Keeping your 1968-1982 headlamps and wiper doors in working condition is a must. This vacuum relay is the main reason for failure or improper operation of the headlight bucket or 1968-1972 wiper door system. Replace your defective unit with our high quality remanufactured Headlamp & Wiper Door Vacuum Actuator Relay. This item is no longer sold by GM and is offered as a reproduction only. In this list, we know of two manufacturers for these valves. One is made very cheaply and the other meets factory specifications and has been in production for over 20 years. An easy way to take them apart is that the metal air tube connections are beveled on the high-end valves, but are straight unfinished cuts on the lower end valves. The headlight actuator relay is installed between the headlight assemblies and extends or retracts the headlight actuator to open and close the headlights. This vacuum relay valve serves the same purpose as controlling the operation of your 1968-1972 windshield wiper door. If you need one valve, please see our other listings. This listing is for 2 C3 headlight relays for use with left and right headlights or one headlight and windshield wiper door. In 1968-1969, only one relay was used for the headlight in the center of the nose near the hood, and one for the wiper on the right fender. 1970-1972 often used two relays for the headlights and one for the firewall or wiper door on the fender. From 1973 to 1982, windshield wiper doors were no longer an option, so a total of 2 relays were used for the headlights.
