I have a 3.8L V6 Mustang. Problem is, when I turn the A/C switch, the blower and radiator fan runs but the compressor clutch does not engage.. it's getting 14.5v from the connector. I've tried "Hot wiring" to the battery with some extra leads and that seemed to work. Freeon is topped off. Could there be an issue with the CCRM? Or am I overlooking something?
