So now i know there is a leak somewhere and the compressor is not getting any power :-/ I checked the voltage on the compressor and it read .06 lol. I tried jumping the pins on the dryer to see if the compressor would engage but that didn't do anything. I checked the fuse which is good. Any ideas? Bad wire maybe? Can I somehow try to jump start the compressor, just give it some juice to see if it would engage? Battery or something?

It could be the compressor relay as well. If the relay is bad, you cannot jump it through the low pressure switch. Most often, I jump it directly at the clutch itself with a fused jumper wire. You have to apply both +12V and ground to the connector on the clutch for it to engage.

Ok, could you explain how to jump it i don't want to burn anything down lol, where would each wire go on the clutch terminal pins?

Should be the same wiring as my old 2k Bravada. If you are looking at the connector on the vehicle wiring harness, there should be a black wire and a dark green wire. The black wire is the ground and should test as such when doing a continuity test. The dark green wire is the +12V feed from the A/C compressor relay.

K i'll try that, i'll post with the results. What about the ac compressor relay? Where can I find that? I know there are 3 relays in the glove box, would it be one of those?
