Yes its a factory a/c car.
I have heat and the blower motor is working. But there is a open vacuum leak that I'm trying to find. When I test the hose going from the engine compartment back to the firewall under vacuum there is none! The engine runs fine and creates vacuum, that's not the issue. My question is that why I have no power going out for the a/c? Dose the a/c heater vacuum switch need vacuum to allow power to go to the compressor? If so that's probably my problem.
