Ive been informed that this is the normal operation on most cadillacs.They designed it this way on purpose to keep hot/warm air from blowing at the face of the driver. This is primarily ment to keep elderly/older people from falling assleep at the wheel while driving. (Most of new cadillac purchases are made by older customers) Studies have found out that warm directed at the face has a tendency to cause peolple to fall asleep more, especially on long trips.
