Man, I cut the truck off and went to do something, came back maybe an hour later and nothing but room temperature air came out, the compressor's not kicking on but it was cooling nice just before that!

I checked the fuse and rotated the relays, then checked psi both on high and low side... The low side has an extraordinarily high amount of pressure (close to 100 psi) but again that's with it not running, either way it's got plenty of R-134a and esther oil...

Any ideas?

 

Sounds like your compressor may have seized. I'd have a pro check it out.

 

Ahhh it's fixed...

I don't know exactly, I went ahead and re-checked everything, this time used a digital multi-meter on the relay and the connections, plus the psi and all, checked all the connections, everything was fine, then I went to turn it on and blammo it works now lol.

Probably something loose or corroded, best I can figure...

 

Will Carnac be able to guess the year and model of your truck?

One possibility is that your system is a hair low on freon. Low enough so the pressure switch is opening the circuit which disengages the compressor clutch.
