Vacuum Supply?
I have a 84 Coupe,and I am working on the vacuum hoses which are dry rotted and broken. I can't find the main supply to the heater/air selector controls. Inside the dash see a {round} valve w/different colors of tubing,and each color goes to a different operation; But I can't see where this {valve} gets it vacuum from? The vacuum line for the heater core shut off valve is not connected to anything;where does this hose route to? Any help would be greatly appreciated............

On later models at least the vac supply line is in the wiring loom.It goes from the check valve behind the dist into the main loom at rear of engine through the firewall and to the control box where it splits to the individual functions as you have seen.
