AIR CONDITIONING CLUTCH RELAY (A/CCR)
NOTE: The PCM PIDs Wide Open Throttle A/C Cut-off and WACF are used to monitor the Air Conditioning Clutch Relay output.
The Air Conditioning Clutch Relay (may be referred to as the wide open throttle A/C cutoff [WAC] relay) is wired normally open. There is no direct electrical connection between the A/C switch or Electronic Automatic Temp Control module and the A/C clutch. The PCM will receive a signal indicating that A/C is requested (for some applications, this message is sent through the communications network). When A/C is requested, the PCM will check other A/C related inputs that are available (such as Air Conditioner Pressure Switch, Air Conditioning Clutch Cycling Switch). If these inputs indicate A/C operation is OK, and the engine conditions are OK (such as coolant temperature, engine RPM, throttle position), the PCM will ground the Air Conditioning Clutch Relay output, closing the relay contacts and sending voltage to the A/C clutch.

Sorry, I confused myself with what you were saying. All you're saying is that the A/C
CLUTCHwon't engage, correct? I had in my head you were saying the A/C
SYSTEM wasn't working.
You are correct about putting the A/C Clutch on a switch, wouldn't want to do that. What I was referring to is on my Dodge. The "A/C Switch" is integrated into the mode knob on the HVAC panel. The A/C
SYSTEM will only come on when it is in the normal A/C position, the Max A/C position, or the defrost position. I basically took that "switch" out of the panel so now I can turn my A/C
SYSTEM on in any vent position.
