AC issues, blower motor working, but somethings gone wrong Options

[aslearvert]

I recharged my AC last year, because it wasnt blowing cold air, but now its blowing cold air. The problem I'm having is that it works great on the passenger side, but no air comes out of the driver side vents. I took off the glovebox, and looked at the blower motor which is working fine. But somehow the air isnt getting to me. What do you guys think is going on? A jam in the vents somewhere? Is there a way to fix it? Has anybody else had this problem? Thanks for your help.
