[QUOTE="MBowman325, post: 1586829, member: 6825"] There's a low pressure switch, so the compressor will run, suck down the refridgerant, and when it gets to a low point, the switch will open and the compressor will stop for a few minutes. If you're low, you'll hit that point quicker. A quick visual test of turning it on and then watching the clutch engage / disengage will tell a little bit. If it cycles quickly then waits a while before it cycles again, I'd suspect that. You can also feel the lines (do not grab them!) and that'll tell you if you're low or not. I always have to refer back to the Internet to remember what that actually tells you though. If you have a FSM for yout truck, it'll tell you details on the AC charge. if I still had the FSMs for my Impala, I could give you ball park figures... [/QUOTE]
