AC worked fine Saturday, but when I got in the car Sunday all it does is blow ambient air. The AC button does come on and I was hoping it was the pressure switch, but VCD states otherwise. It appears the HVAC relays isn't getting a signal from the control circuit, but what actually controls it? Fault code is below, I can post the full log if needed.
Any info or help is much appreciated!
