Automotive Air Conditioning Information Forum

I need the normal AC gauge readings for my Van if anyone knows them? I have been everywhere on the net and the chilton data base and can't find them. tyring to diagnos my AC problem. AC blows hot and has the correct amount to pressure. I have even had the system evacuated and refilled. No Leaks and holding pressure. Compressor working and clutch engaging. Any help is greatly appreciated

I should have mentioned I have a ProAir System as well.

What are your pressures?

Is the "Pro Air" some sort of rear evaporator that tees into a stock front-only system?

All cars work about the same, "good" pressures are dictated by the physics of R-134a rather than the design of a particular system.

What is your suction pressure (low side)? - you have a high mount HT-6 compressor I assume, that may have imploded suction reeds- does compressor turn really easy (engine off) with one finger- with little catches as it rotates? If suction pressure is above 50 psi - you have compressor issues..
