ac clutch not getting power
I was wondering if some of you A/C experts out there can tell me what all there is on my 2003 ford ranger edge 4.0L that the ECM takes data from that would cause it to not switch on the clutch. I have changed the cylcling and high pressure switches also the dash switch and the throttle positioning sensor. I have a fully charged system and can force the ac clutch on by jumping a wire to ground from the appropriate relay prong and it will blow cold air. I have also jumped out the high and low switches in case the new ones I bought were bad still no luck. I really hope my computer is not to blame. Any ideas or info would be greatly appreciated.
