I went out for a drive and collected some data with my handheld logger. Outside ambient temperature is around 57F, set the AC controls to 60F.

When the AC is not working, it looks like A9 (AC Compressor) is at 100%, like it is trying to call for full compressor, but nothing is happening. The high side sensor is saying we are stuck at 5 bar, which is validation nothing is happening.

When the AC kicks in, the control unit stats regulating the compressor by reducing to 55% and my evaporator gets cold, cold air comes in through the vents, and the high side increased to 7 bar.

What is going on? Compressor dead?
