"IF YOU HAVE HEAT COMING INTO YOUR INTERIOR ALL THE TIME YOUR A/C WOULD HAVE TO WORK EXTRA HARD,EVEN MORE ON HOT DAYS." no one said that there was heat into the interior of the car, what was described correctly is the diverter air door has a built-in stop to prevent the door from totally closing off the air flow on a 67 gto with factory air. That air goes back to the blower motor through the factory air hose directly into the motor.
"Funny, I don't have heat coming into my interior all the time. Wouldn't that be an asinine way for Pontiac to design an air conditioning system?" There is no heat going into the car. By the way, GM and Pontiac always had water and air flow thru the heater boxes with factory air system. This keeps mold and condensation from building on the heater core when the AC system is on. "My door does close all the way ...Possibly it is time to fix your door" If your door closes all the way on the kick panel end of the AC heater box then the stop is missing and it is not working properly. "If the heat is not switched on and the blower not running as is always the case in the heat of the summer, you will not be giving up any heat at the core so, by not circulating all the water in the radiator you are losing cooling capacity" Did you notice that from 1967-1972 all the GM blowers usually ran on low speed in any heater position including off. There was no off switch position for the blower motor itself. "I think blocking the heater circuit, not just connecting the lines together like I have seen some do, will actually make the engine run a little cooler." I totally agree that blocking off the heater is the only way to do it, not connecting the lines together.
