Quick question on my new 5.0's climate control. I don't know if it just started doing this or if it did it when i purchased it and I just didn't recognize it.

If I have the vent selected to floor, i get air out of both the floor and defroster vents. If i select cabin and floor, I get all three. And if i select just cabin or defroster, i only get cabin or defroster. Is this normal behavior to get defroster air when selecting floor or cabin and floor? It takes a good chunk out of my floor vents air. I'd venture to say 80% defrost 20% floor, but it's only 10% defroster when i select cabin and floor.

Is my climate control out of whack? Is their a reset procedure or should i just take it in?

Thanks.
