Intermittent AC - out of ideas

AC works some of the time = clutch will kick on. Intermittent.

The scan tool will show live data for the HVAC it's buried but find it. It will show state of compressor and AC button for example. Also with car running 30 seconds command compressor should be long enough to feel some cold or hear the RPM drop.

+1 on high/low gauges. It's the only way to diagnose AC. Especially with variable gain compressor.
