I upgraded my alternator, positive/negative wires and engine ground for my subs. Now the A/C clutch won't engage and both radiator fans don't turn on. I checked the relays/fuses and they're all good. The new wiring is getting good power/ground too. Could my PCM be the issue? I've done this exact upgrade on a 2003 Regal GS and had none of these issues. (problem solved, A/C needed to be recharged.)
