The center vents are just that and will only blow outside air or a/c air. All other vents work with the heater controls for temperature. So I would check to make sure that you have both heater control knobs set to off or the arrow pointing down. If they are in the off position you might need a new heater control valve, or adjustment on the heater control knobs.
