When you turn ac on or go to choose climate (touch display) the passenger side temp keeps sliding up/down on its own, same for mode between legs, defrost, etc. If you try to hold the temp down it would stay but if you let go it keeps going up and down, the mode is more problematic since air keeps going between the different modes quickly, so you don't get a smooth air coming from center air vents. Ever seen that before?
