alright, so here is the problem. My a/c works fine at idle but when I start driving it cuts on and off. If my engine is not under a load then it works fine. I scanned for faults and found the pressure switch code. I replaced the pressure switch, charged the a/c and the problem persist. I didn't notice it doing this until I went with my p16 file and supporting mods(then again I hardly ever use my a/c). So what do you guys think the problem is? thanks for the help

ps. the fans are working[:)]

you have to figure out exactly why it's cutting out. are you losing power to your clutch? or is it an internal compressor problem? how did you charge it? are you sure you have enough in there. because if it's undercharged, then the compressor may work fine at idle but kick out once the pressure gets too low on the low side since rpms went up....need some diag info.

One you replaced the pressure switch behind the front bumper, do you still get the pressure switch fault code? What is the exact code that comes up?
