NC WTB: Vacuum Selector for A/C Control - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Does anyone have a NOS, good used one available? My current switch is has two vacuum ports , but can convert to a 3 port system.

Tried to rebuild mine - holds a vacuum now - but will leak in between settings.

Thanks,

Frank

PS Will consider a control as well.

Not positive but i think one side is suppose to bleed off between settings.

I would love to see a vacum diagram I have to attack mine this summer

bikerbuck - Hmmn - I wondered if that was by design.

Anyone else weigh in?

Hottrucks: You can check my thread in the message board. The community was kind enough to supply wiring and vacuum routing.

Frank..Believe it was by design, If your leaking through the valve itself and are testing the side that goes to your actuators it will bleed off between settings. This wont ever be a problem because it wont get vacuum from the other side (Vacuum source) in that position. IF that makes any sense.

Hey - well I might be ok.

The air has not worked for so long I did not remember. Will try it again today.
