Vacuum Relay Valve Corvette at Melissa Eide blog

Vacuum Relay Valve Corvette. Afaik.what you describe on driver side raised ridge is headlamp relay. Remove the filter at the base. Relay valves control vacuum to the headlamp actuators to open and close the doors. Vacum is a negative pressure atmosphere and positive pressure atmosphere must fill the negative to balance out. The two items under the nose are headlamp vacuum valves. So, i thought i'd give fixing it a shot. The purpose of this paper is to illustrate the normal functions and associated vacuum and atmospheric pressure states of the vacuum operated headlight extension and retraction. Disconnect all 4 vacuum hoses. I was almost set on converting the headlight tilt to electric, but the more i examine the original vacuum system, the easier it seems. A vacuum relay determines which side gets the vacuum. You can test the relay by simply connecting a small vacuum line to the control line, and another line to the source (yellow) port.
