Most cars have either a cable or a motor system to alter the air dampener valve/s. When you alter the setting do you hear any noise of a motor or the thump of the valve closing? My Ford had foam rubber as a seal around the dampener door it got sticky so it wouldn't open. You may need to locate the valves under the dash heater/cooler box. Try moving them manually.
