The air conditioner in my 2015 Stingray will not blow air from the main vents on the dash. Has anyone had this problem? If you have, how was it fixed? One mechanic says the sensor in the dash are not letting the door open for the main vent to blow cold air. He said that the dash would have to come out to fix. I am leery about the dash coming out & causing other problems. Any comments would be appreciated.
