A/C Question
I am trying to diagnose why my A/C won't work. It is a 1999 with a 5.9 which I purchased used knowing it needed work. Question is am I missing a wire going to the compressor? And if I am, where is it supposed to lead to? The compressor does not kick in at all. It is a 1500 if that matters. Thanks.

Okay, everything is back together and plugged in. But A/C is still a no go. I used a curcuit tester to see if I had power at both the M.I.A. plug and the the plug from behind the clutch but theres no power at either. The clutch is not cycling, It won't spin at all. If the system was empty would it cause this?

If it was completely empty the compressor wouldn't run. If it's low but not completely empty the compressor will kick on and off as it's only on where there is refrigerant coming though. I wonder if it's a more serious problem since they disconnected it. You could try to have it charged and see if it makes the compressor come on. If you do that or any other A/C work do it at your own risk as it sounds like it can be dangerous. A buddy also told me never to touch the compressor while the truck or a/c is running as he lost his finger like that. So just be careful and do everything at your own risk.

The guy told me the A/C ''blows cold'', but the truck wasen't running when I bought it so no way to know. Judging by the location of the plug, I think they accidently left it there when it was put back together and were to lazy to do it all over again. I understand your concern over offering advice, any opinions on throwing a can of refrigerant like the one's the parts stores carry? Thanks again. Oh, I did check the comp. fuse and relay and both are O.K.
