Hi All I have 2009 Audi Q7 Prestige S-Line Calla White. I am facing a problem now. I am not able turn off the A/C for the back seat. On/Off button don't do anything and temperature settings stay same number for always. If I try to change temp or fan speed I will see "---" in the display. They never change. It was working before and I know I messed up something. This is a new car to me. I bought it around 2 months back

Do you guys have any idea how to turn of the back A/C ?

Thanks
