Rear Air Con in T7 Ocean doesn't seem to work

[thehoggmeister]

I have finally got round to finding out how the rear Aircon works in our T7 California Ocean. It has 3 zone climatronic air con. No matter what I try on the infotainment head unit I can't feel any air blowing from the rear roof vents or from under the floor.

I have the vents open and the Clima control shows that it should be synced with the front. It is not locked out. I am thinking there may be a setting in the California panel.

Am I missing something really obvious to turn it?
