I have noticed that the air coming out of my vents is always about 10 degrees warmer than the outside temperature even if it is cold outside and the car has been out of the sun.

Late at night when it is in the 50's outside, once I have been driving for a little while the air coming out starts to get warm.

I have the **** all the way on cold, fresh air intake in on, yet the air is warm.

Is there a calibration of some sort that I can do to get the **** to truly not heat the air when it is all the way hard over on cold? I would think that if I have the a/c off and the **** set to cold the air I get should within reason match the outside air?

 

some of that air is also coming from the engine compartment :-s
