New member...need help!
Hello everybody!!!
I run a general auto repair shop here in N.C., and have a couple of customers with vintage Vettes....all of them sharp cars. Sometimes I run into a little difficulty getting repair info on them....and I've run into that very problem now.
I've got a 1980 vette here with an ac/ vent heater door problem. I've narrowed down the problem to the vaccuum switch on the a.c controller being bad. I got a new(?) one from Eckler's, but it won't pull any vacuum through either. I can hook vacuun to the port for the black line, and none of the other ports gets vaccuum when I switch it....it's bad....right?
I've also noticed that the vent doors (which do work if I apply vacuum to the connector) do not seem to be opening and closing when they're supposed (when the switch does work occasionally). If somebody has the vaccuum diagram or a pic of the ac/ heater system controls, I would deeply appreciate the info.

Hello and welcome to the forum from NE Ohio.
I found this thread in the C3 Tech/Performance section that has reference to a 1980 with a 1977 diagram. Check out post #32 in this thread. Good luck.
