: A4 1996 2.6 Auto Aircon circulation problem

Recently with mainly hot weather conditions, the flap which determines either outside air or internal recirculate is switching of it's own accord between the two functions, often during driving, 'without' the actual switch on the control panel being applied.

The function, outside air or inside air, in the past was always fully controllable with the appropriate switch. I'm sure this is the normal state as I've had the car since new.

Now, once the inside air activates, you cannot switch it off, which is okay some of the time, but I don't think this is ideal and even the manual recommends that the aircon system should not be run in this mode continually.
