Ac/heater connection thru enfotainment system

Hello, I would say if the infotainment system does not show the climate control functions, I would suggest it's more a software issue than a fuse issue. I would suggest you will need professional hands on testing to figure out what's going on. It's too complex for a forum like this. Get some expert assistance.
