NO REAR AIR CONDITIONING

2000 Chevrolet Tahoe • V8 4WD Automatic • 87,000 miles

I have a 2000 tahoe LS with rear air. Just had new compressor, orifice, drier put on, have great air in front but warm air in rear. Is there a orifice in this rear system? Could itbe a blend door actuator? Any other possibilities?

Suspect expansion valve{TXV} on inlet line to rear Evaporator. See diagram. Remover cover and panels to get to EVAP if not cool afetr TXV then it is stuck shut
