On my 83 Cutlass, I'm looking for the vacuum control valves on the back of the AC control panel. I can find the 9 port and its on order. But I can't find anything on the 2 port that is connected to the temperature lever that controls the heater valve. When on MAX it allows 100% vac to heat valve to keep it closed.
Can Anybody help me find the two port?

You are in luck!!!! Sort of. It's part number 7897420 or AC Delco 15-7975. For whatever reason, I tried looking for this before and couldn't find it. But I looked again and found the part number for BOTH the 9 port and the 2 port. 2 port has been discontinued for a good while. 9 port can still be found under p/n 16037778 or AC Delco number 15-71389 or aftermarket parts equivalent. GM list price for the 9 port is $141.89. As far as I know, the 2 port isn't available aftermarket. Saw a few of the 2 port ones on ebay and from various sellers.

BTW- they used the SAME 2 vacuum switches in the Cutlass from 78-88, it just doesn't show it here since the book only went back to 1982.

Another source is 1991-1993 GMC and Chevy VANS with A/C. They use the same 2 port switch. So if you found one in the junk yard....
