Symptoms are indicative of failing dash control unit .. *Hands-on* testing required. Possibly scan test BCM will help. (Body Control Module)

The way I see it IF problem within is the HVAC unit itself - it wouldn’t be same for each zone.. Hard to imagine the same failure is present for the internal mechanical baffling that is also responsible for temperature control - dual zone.. But then again that’s only an online theory.. of course.
