I have an '03 TB with 85k, when I park the car in the sun and it gets hot the a/c will blow out of the floor vents for about 10 minutes. When the interior or the space behind the dash cools a little the vents on the center of the dash will come on. I have an LTZ with the automatic control. Does that control unit overheat and default to the floor vents? Is there some other problem? I am thinking I need a new controller.

Thanks for any replies,
