Does rear climate screen and controls in Sensus also not work? That could point to whether it’s just a display issue or something more sinister.

I have 4 zone and in second year they had to do quite a bit of work under warranty as the rear did not blow cold air. There was nothing indicating anything was wrong - all controls were functioning.

I’ve never experienced what you describe and I have been through all the menu options in Sensus. I would love to be able to put a lock on it to stop kids messing around as the Volvo primitive 4 zone system makes do with only one fan.

You can definitely do the battery disconnect and several restarts to get all systems to reinitialise.
