Hello, I have 2002 S60,2.4 D5, and I have one 'problem'. At higher speeds, when aircon is off (**** is turned far left,led is orange), air keeps coming in the car through ventilation holes, if temperature **** is turned to hot, hot air is coming, and if it is turned to cold, cold air is coming. I am wondering, is this normal, and could this be stopped, because, when I turn off aircon, it is logical that I don't want air to keep coming in the car from vent holes.
tnx

 

It is normal due to the "Fresh air system" it is to keep fresh air moving through the cabin at all times.

 

OK,tnx
