- 2016 Buick Regal GS
2016 Regal GS AWD. I often turn off Auto and AC to just have fresh air venting through the car. But it always happens that periodically, the system will turn on freezing cold air and run it for several minutes before returning to fresh air vent. I end up freezing for those few minutes and can do nothing to stop it. I do have Auto Defrost on, but the cold air is coming from the front vents and floor vents...not the windshield vents. Any ideas? I'm 2000 miles short of 50,000 miles when the bumper to bumper runs out.
