Will It Cool or Not?

Hi Bob,
I have a '96 Mazda Protege which I think is a reliable car. I have just one problem that concerns the car's air-conditioning unit. Probably one out of ten times that you turn the aircon on, it just blows hot air. I have to turn it off and make sure that I am stepping on the accelerator pedal when I turn it back on. If I'm not stepping on the accelerator when I turn it back on , no cool air would come out of the vents. I have brought the car to the shop twice, but the only solution done was to always add freon, which didn't solve the problem. What do you think is wrong?

First off, a '96 should not repeatedly need freon. These are sealed systems that do NOT CONSUME FREON. If the system is low, then there is a LEAK! This I can guarantee! As for stepping on the gas to get it to work, that should have the opposite effect. You see, when the car see an added load, like stepping on the gas to pass, it turns off the AC to give the motor some more power, not the other way around.
Good Luck!
Drive Safely!
