Anyone have any wiring diagrams? Need electrical guru\'s! Even though Im not home, Im still rattling my head about the AC issue- (6.2 92k2500 pickup) At first I thought it was the head unit (the electronic box) that was the cause of all the problems- I cleaned the terminals several times, even tried adding new solder on for better connection. This works for a while, but once I reach any speeds, it just shuts itself off (the compressor) and the "AC" light starts blinking. This has lead me to believe that somehow the RPMS is invovled, but im not sure how. If I reseat the head unit, its ok again, but after a little bit of driving, it will stop working. If I unplug the batteries and reset everything, it will also work again. This is leading me to believe some electrically activated switch, that gets constant power- is holding something open. None of my chilton or Haynes manual specifies any switches- but again, they dont have the diagrams either- I've tried unplugging the plugs on the receiver, and also on the compressor, but neither of those reset the system. My guess is pointing to a relay somewhere, and if anyone has any ideas where that relay is, it would be greatly appreciated!
