2000 f150 Super Crew 4x4 with no power to the AC Compressor... All fuses,relays and diodes good. Tested both high and low sides with jumper wire with no change. Checked local grounds. When i check the comp wires with a voltmeter, Im getting a very slight reading, but its way less than 1 volt. Anyone have any suggestions on what I should try next? Thanks !!
