Climate Control/AC Compressor/Clutch not working. Doesn’t blow cold at all

Turn Climate Control to Max AC and blows ambient temp air only. Heater, blower and blend doors switching works fine.Pressure Sensor has 5 VDC Ref Sig.(IN) with 1VDC(OUT) and it’s Ground. No +VDC to Air Conditioner Clutch or Engine Cooling Fans (high speed). Supply +VDC to clutch connector on compressor and clutch pulls in just fine and not only does compressor sound and work well the engine cooling fans come on also. I believe my issue is in IPDM or an open in wire returning from switch in compressor to IPDM. I need more info such as wiring diagrams, pin outs and direction to test further. Any assistance would be greatly appreciated, thank you in advance. Tim
