C2 a/c heater vacuum switch

[Bruce Boatner]

Does anyone know of a good source for the vacuum switch that mounts on the air distribution box of a factory a/c C2 (1964 in my case)? This is the switch that supplies vacuum to the heater control valve. A vacuum line runs from the intake manifold to the switch and another vacuum line goes from the switch to the heater control valve.

I recently discovered that a prior owner removed the switch and spliced the vacuum two lines together. As a result, vacuum was continuously supplied to the heater control valve which allowed a continuous supply of hot water to the heater core regardless of the temperature knob position. Helped explain why I had always had warm air in the vents.

Thanks!

You can do one of two things. Use a 70s plastic switch or get a repro. I think that Long Island Corvette has the repro.

Wayne,

Is the '70's plastic switch still available from GM?

Both Long Island Corvette and Corvette Central list the AC Heater vacuum switch at around $50.
