Start the truck without the ac on. Then have someone turn the knob to max ac while you stand outside the truck with the hood open. You should hear the compressor kick on. It will be a hissing noise and you will see the compressor clutch release and go into gear. Most of the time thats your problem. Bad clutch. Check that first.

ok, is the clutch suppose to go on and off?
cus it go on and charge up, then go off..... so on
