the best advice for the heater / ac question is to install heater shut-off valves so that no hot water comes into the interior of the car. This helps reduce heat 2 ways. There is some heat transfer in the tubes running through the console and the air blows through the heater core and then through the evaporator so that unless you can completely shut off the heater valve there is some hot water circulating through the system. the cable on the dash does not allow the heater shutoff valve to close completely. Installing heater shutoff valves in the engine compartment keeps all of the heat on the outside of the passenger compartment
