Dodge Ram 2500 Defroster

I have a 2003 Dodge Ram 2500 and am having trouble with the heating ventilation baffles closing to redirect warm air to the windshield. Is there an easy way to get the baffles to close?

If there’s a physical obstruction, remove it. Check the vacuum or electric device that controls the flap. If it’s bad, or disconnected, the flap won’t move.
