Could someone tell me how can I get a fresh air from outside when my AC is off (Econ mode is on)? It seems like when turn my AC and just use fan to ventilate air from outside it for some reason blows engine warm air inside the car...
I have asked the dealer and they say that this is normal and that is how it works! But I totally disagree with them.
Here is an example. You drive during the day when temperatur is forx example 80 degrees, then around 6pm temp cools of down to 70 and you turn your AC (set to Econ) mode and at this point want to get 70 degrees cool air from outside but I can never manage that, it always blows warm hair no matter what temperature I set.

Can someone help please?
