I have this A72F fault as well. As far as I can tell the AC works as intended never have I had an issue of Warm air when I needed Cool Air, ect. So my OCD kicks in wanting for all the little boxes on ISTA+ to be green. I've ran through all the suggest test procedure which activates/deactivates the magnetic clutch and your supposed to listen for a click but I never hear it. Whenever I push the Max AC button the air is ICE Cold. So I'm confused.
Did you racermp ever solve this issue?
