GMC Envoy XUV SLT: I have a 2004 Envoy XUV. The AC isn't working

Customer Question

I have a 2004 Envoy XUV. The AC isn't working, but the refrig pressure is good. Is there a chance that a thermostat for AC isn't working, or some other switch? I know that the dealers will simply want to replace everything, which would cost about 1/3 value of car.
Any troubleshooting tips I can try first?

I am sorry for the long waitwith the truck ON and the AC set to high if you unplug the 2 terminal switch on the aluminum accumulator and jump the 2 terminals in that connector you unplugged will the compressor turn on ?
