Check to make sure this shaft is properly inserted into the vent damper receptacle or you will not be able to direct the airflow. The air directional dampers are all manual, not pneumatic, so the air line is not the issue here. Good luck!

Hmm.. interesting. I haven't removed the radio or the face plate so is there a chance that this shaft has fallen out on its own? Is this a common thing? How much of the interior do I have to pull apart to check this? Just the radio? or more?

Sorry about the barrage of questions but I have been on a steep learning curve since owning this little beauty.
