Where to find a heater control valve

easyrider said
My 65 dart has the push button control for factory A/C which has two vacuum lines to the heater control valve. I'm guessing that is to be able to control the flow of water in order to adjust the A/C temperature. The valve has a double diaphragm so it can pull from either side. I have seen these but can't locate one now that I need one. Anyone know where I can find this item?

I am looking for one also for my 66 Barracuda with factory air. Hope someone has a place to get one.

I "might" have a couple of used ones but unknown if they're a working unit. I'll look and see what I have tomorrow.

I do have a pair of used vacuum control units that have the vacuum pad and water control valves. I did test the vacuum that I either opens or closes the water valve and that does work. I think the other side of the vacuum unit has to function in conjunction with some other operation as it wouldn't do anything. Looks like both water valves do let a very small amount of water through - but not knowing the system - may be the way it operates. To verify, I'd have to get my NOS valve out of storage and check to see if it does the same thing..
