AC question
I am working on a 1988 Deville. AC is blowing cold air but comes from floor vents. After 15-20 mins, it will begin to come from dash vents. What's up with that? Temp control center has no button for which vent to use and with heater it should come from floor vents. How does it know where to send the air? Help me, please.
