ANY AUTOMOTIVE AC EXPERTS OUT THERE? I'VE GOT PROBLEMS..........

Troy, with only 5 oz in the system the compressor will not cycle as the system pressure is too low. With the key off can u see that the clutch is disengaged? With the key on and engine off what does the clutch do? Is it engaged or not? Does it only engage as soon as u start the car? Kim

I never thought to check it with the engine and key off. However, I did put the old switch back in with the system totally empty, and the compressor does not come on with the ac activated as it did when there was 5 oz in the system. The new switch that I tried, caused that fans to run full with the key switch turned on. and the engine cold. I assume this new switch is faulty.
