Tex g Posted October 12, 2020 Share Posted October 12, 2020 Numb I have a 2011 mack cxu613. AC quit workig. The AC and recirculate light wouldo longer illuminate when I would press it. I downloaded a wiring diagram and circuit number 1 on the smaller plug did not have 12 volts. I used a jumper to get 12v to it. Things turned on momentary. But the wire got hot. Unfortunetly this is about where my troubleshooting skills end. Any advice would be greatly appreciated.
