I installed my PFC and the AC refused to work, so I did Chuck Westbrooks AC fix of bypassing the ECU and everything seemed to work great for one day.
Now, starting last night, the AC will run and get extremely cold and then shut off and blow humid air. I have to turn the fan off and then back on to get the AC to kick back on. Sometimes I have to turn it off and on a few times for the AC to come back on and other times it makes no difference how many times I turn the fan off and on.

Both last night and today I was able to get the AC to stay on with the fan set to 4, but I don't know if this is a fluke or not.

Does it sound like I need a recharge, is the AC freezing up, have I missed something else?

Even when the compressor cycles off the air shouldn't get humid like it does, so what am I missing here?

 

If the a/c does get super cold, then goes warm, the system is freezing up. Mostlikly whatever you did you get it to work also bypasses the pressure/temp. switches, that control the compressor cycle.
