Puzzling Ac Problem

[bplaney]

The AC started pumping out hot air a few weeks ago. Here are the facts about my system:

1. The clutch works - no funny noises, everything smooth

2. I put in leak sealant and refrigerant combo with leak detecting color into the low pressure side - no leaks. Pressure is 50 lbs.

3. I went to AutoZone and had them connect the diagnostic tool - NO ERROR CODES anywhere

4. I borrowed the gauge setup from AutoZone to test the high pressure side - 125 lbs. - and when I removed the fitting there was a puff of released gas (like when you remove the nozzle from your car tire's stem after filling it with air) and there was a green color to the mist, so I suspect that was from the leak detection color from the sealant/refrigerant. I don't know if the pressure should be higher than this, but there was pressure.

Bottom line: the parts of the system around the engine compartment seem to be fine, and there are no error codes showing on the diagnostic tool.

Any ideas???
