I fixed the problem it just ended up being a bad replacement compressor as I got it from a junkyard I bench tested the compressor and the clutch wasn't engaging. I went back to the junkyard and got another compressor and I bench tested that one and the clutch engaged. Put it on the truck and took the freon no problem and its blowing cold. Thanks for the help.

nope I don't let anyone work on my vehicles. but I will vacuum out the system and add the right amount of oil and freon.

I just replaced my ac compressor and my tensioner as the tensioner was seized. I made sure all lines were tight and that everything was connected. The compressor doesn't seem to be taking any freon. Obviously the clutch ins't going to engage with no freon in the system but what am I doing wrong. Should I jumper the pressure switch with a paper clip so that the clutch engages? It's a 2005 GMC Sierra 1500 with a 5.3 vortec if that helps. I would appreciate some help here thanks.
