Every couple of weeks the A/C on my 2008 acts up. It seems like a damper or diverter closes, preventing air flow through any of the ducts. You can hear the fan, and the trickle of air that comes out the ducts is still chilly, but no air flow out of any vent even if you crank the fan to the max. I will be going to the stealer to have it checked out, but since the problem inevitably will not surface when the car is in the shop I wanted to see if anyone else has experienced this issue or knows of the problem. Thanks!
