Why does white air come out of the a/c vent?

Asked by anthjal Sep 13, 2013 at 02:11 PM about the 2010 Chevrolet Silverado 1500 LT Crew Cab 4WD

Question type: Maintenance & Repair

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?

he might mean condensation in the air (looks like a cloud coming out of your air vents) I have had it happen before when it is super humid outside and my air is blowing really cold

So what is the problem with a/c. I have the same issue and they cannot find a leak. They told me that the evaporator core had to be replaced.
