If it is blowing freezing cold one minute, then cold the next, I would suspect it may be overcharged. Mine did that until I had it checked/corrected. I also noticed a performance problem while it was happening.

#5 of 7 A/C and Vent Problem by kmanka

Jul 31, 2012 (9:19 am)

I have a 2008 HHR and the A/C works great...that is until about a week ago. It is the most bizzar thing I have had happen. When the A/C is off the vent will not blow right. What I mean is that it ususally blows hot even if the outside temp is cooler. Now the A/C works but it is strange too. It will blow hot air if the dial selection is set to Max cold, but if you move it up one click it goes into full cool mode. Does anyone have a clue as to what is going on?

Hhmm A/C and milage drop, potentialy could be related I suppose. Has the A/C system had any work done on it?
 
My 06' had an issue right from the get-go where if I put it on max it would cool (almost super cool) and then would get warm (without me touchin anything) and go back cool. Plus when this was happening I could detect a engine performance problem. I had already heard of some that had an overcharge of coolant that created the problem and had it checked at dealer (I mentioned overcharge as possibility), don't know exactly what they did , but problem was corrected.

No work done on it and the gas mileage does go up or down with the A/C. Not an overcharge as I have had the vehicel for several years.
