Okay, its getting warm now and my 1979 vette ( without AC..hoses are ther just no compressor) is making me sweat even with the tops off. I would like someone to tell me just where the "fresh air" enters into the corvette. My AIM talks about cowl plenum but I just can figure out how air get into the ductwork behind the dash. No problem getting heat and when the car is sitting still with the heat control on "heater" but temp set to "cold" there is axctually "cool air " coming out at the feet area from transmission hump vents. There seems to be a vent door operated by a vacccum diaghram( but doesn't work...even if it did I think it only recirculates inside air)
If I new how the outside air got into the system I could check to see if it is blocked. When I switch temp setting to "hot" wow it burns you up. I just thought the "cold " should be colder than it is.
Any help would be apprecited( especially before I head the beach)
