Hello I need some help ready to blow this car up>>>> I have a 2008 p71 I'm not getten any power to the a/c clutch..I have power to the switch tried the pinning still no power I have 12 volts on everything both pcm slots when I turn the switch on all fuses are good the relay is good in fuse box. from what I read about it. it should be working.. I can't find any info about the 3 wire high pressure sensor I have 5 volts on 2 of the wires nothing on the other pinned that and still nothing ,I must be missing something if I jump the relay it works, any help would be great.. it was working and then just stopped 35 psi on system
