Need help with AC problem

Hi,

My AC went out a few months ago and I've replaced just about everything: compressor, AAC, pressure switch, dryer, and expansion valve. Vacuumed it down and charged as much as I can without the compressor kicking on (doesn't leak). I've checked the fuses, jumped the relay and still cant get the compressor to kick on. Computer says no AC related errors. Any advice would be appreciated before I swallow my pride and take it to the stealership.

Thanks in advance.
