Tri zone cooling - air con on passenger side is freezing cold and won’t warm up

[Gen6Original]

My aircon on my T6 Caravelle has three zone climate control. The passenger side is constantly cold. The driver and rear are all working fine. Not sure how to fix this?

Also I am opting a lot of whirring / clicking / sounds like bubbling water but I think they may be actuators in the dash behind the radio area when I turn the van off. It goes on for ages and don’t sound very promising. Any ideas?

Quick update. I have done the reset trick which seems to have fixed the soft flap, and now getting even temps out both sides.
Not sure if this will sort the whirring out but time will tell.
