With older vehicles this was easy, because it just meant that a cable needed to be adjusted. However in newer vehicles even with manual controls the parts are often motorized now. Best option, take to a dealer so they can fix the control valve. It's moved by a small servo type system that can sometimes become jammed. (Debris/breakage as it's plastic etc.) GM has used this system for air flow direction control for over twenty years now.

1991 Chevy G20 van- Why won't airconditioning blow out of dash vents instead of defrost and heat vents?
I had a Chevy van of this vintage and I found a vacum hose leak in the controls that would make the heater/defrost door default too defrost open. lisining carefully under dash or under hood may pinpoint leak.

How do you fix an air conditioning problem where most of the air gets directed to the floor vents instead of the main vents and defrost vents in a 2000 Chevrolet Malibu?
When you adust the switch on your dash to direct the heated or cooled air you are actually switching vaccum to vaccum servos that open and close the doors within your heating/cooling system. If you drop your glove box door you can see behind it to witness this happening. You may need to remove some of the plastic dash covers also which is easy to do.You may have a bad vaccum line, vaccum switch or if they are all working, you may have a broken door within the system.
