Air con is working fine on driver's side but warm on passenger's side. Before I book the car in with Audi I want to try and locate the heater flap motor to see if there's any issue with that. I've had the glovebox out and there are 5xV157 actuator motors. My belief is/was that they all controlled air flow rather than temperature but I am being lead to believe that the bottom-most one on the side of the centre console may control the temperature doors but looking for confirmation either way. Can anyone shed any light on this for me? Any pointers would be gratefully appreciated. To rule out the problem being low gas levels I have booked the car in for a recharge.
