Why does white air come out of the a/c vent?
Hello,
I have a 2010 Silverado and it has 39k miles. About 2k miles ago, white air started to come out of the a/c vents sporadically. At that time, the a/c was colder than ever. Now, though air comes out, it is not cold,(not hot either). A whistling sound also started to come out of the hood upon acceleration after I had the throttle body replaced. I do not know if they are linked. Has anybody had this problem before?
