Hello everyone, I have a 1999 Dodge Durango 5.2l SLT Plus... I've been working out a couple issues next project is getting some cold AC and warm heat going.. just got a new ac compressor as I'd seen my old one not "catch" the clutch but had same problem with new unit, turns out it wasn't the compressor but my wiring is the problem.. I know this cause I hooked new compressor up directly to battery to test it and it worked.. but when hooked up to its harness nothing happens just a little cool air but clutch doesn't spin.. checked relay box all pins are dead no voltage but relay is good.. which pins should be getting power? Also no heat at all not even a little warmth
