My Air Conditioner hasn't been working since I bought the truck and I had a guy at my work look at. He bypassed one of the sensors and the A/C Compressor started spinning but made very bad noises. He told me that that sensor is bad, and the clutch is bad on the A/C.
So after looking online, (I get a discount through napa and kind of wanted to go through them, but if you guys know of a cheaper place, let me know) I found 2 clutches.
They are as follows:
Just to save you some money, because he jumped the switch doesn't mean its bad. The fact that the compressor came on when he jumped it means the switch is probably working properly. Lets say it was the low pressure switch. It will not allow the compressor to kick on if the system has low pressure(which is probably your case). I'd just do the compressor/clutch, then get a recharge and it should be good.

I'd be real suspicious that the compressor has a problem. Before you invest in a clutch, you really ought to have somone put a set of guages on it to see if there's any refrigerant. Here's a typical scenario - the freon level drops due to a leak, and since the lubrication oil is carried in the freon, the compressor runs without adequate oil. Due to age or lack of lubrication, the compressor piston seals fail, or the compressor develops a knock or rattle. The low freon level will deactivate the system to protect it, but a basic truth is this: if the A/C system has been inactive for very long, you need to be prepared to make a comprehensive repair to ensure proper function and to avoid wasting money. You may be lucky and just need a shot of freon and a switch, or you may waste money putting a clutch on a bad compressor. What I'm trying to say is, with AC work on older vehicles, it's rarely a simple cheap fix. Just be prepared, and don't get disappointed if it's not the clutch.
Well I went to Wal-mart and bought some refigerant relfill stuff and the guage on the bottle said it was charged. So I don't really know. (Not to argue with any of you) the guy who looked at my truck manages the whole fleet of trucks my company has and seems to be pretty knowledgable.
