    Make sure that the pressure switch is good. A lot of times they will go bad and won't sense that the pressure is there so it won't put power to the clutch. If you have a reqular 2 pin connector to your clutch, unplug it and take 2 test leads to the clutch from the battery and it will turn your clutch on if its good and that will giuve yo the chance to see if your a/c is blowing cold air. If so its probably your pressure switch.
