2001 v70xc Air Conditioner Clutch does not engage

I have a 2001 v70xc that I have done a ton of work on. My latest issue is the A/C. The clutch will not engage under normal circumstances. I replaced the CCM with a used one off ebay. Most everything works on the CCM - fan, auto setting, A/C switch turns on and off with green on/amber off. Not working - seat heater buttons, defrost buttons. Anyway, back to the A/C issue, I removed the whole compressor unit and removed a couple of the shims (washers) from the clutch. The gap is now at .3mm, which from my research seems to be the acceptable amount. I am able to jump the clutch relay and it will kick on. It does blow cold air out of the driver side vents. I tested the refrigerant pressure when I jumped the relay and it was within the green reading (about 35 psi) while the A/C was running. Any ideas as to why the clutch still won't engage? Is there a pressure sensor somewhere that I don't know about that I could test or replace? If so, can you tell me where it is located? Thanks all!!

I also switched the relay and verified it works. I switched it with the wiper sprayer relay and it checked out as working there.
