HVAC Problem

I have a brand-new C350 4matic sedan with less than 1000km on it. When I use the ventilation system (i.e. window defrost, front vents etc) no air comes out unless I use the recirculate option. Does anyone know what the issue might be? I'd bring it to the dealership but they are 3 hours away from me right now. Any suggestions??

There may be a real issue that needs attention.

One thing we have noticed is that when the system is set for full automatic mode is the airflow is coming out all kinds of vents and the center vents get very little flow. Changing to manual settings and telling the system where we want the air to blow can help a lot without using the Recirc mode.
