My A/C stopped working. But seems to work. Just not blow the air out of the vent

What is your question?

I've gotten to the two actuators that I thought were directing air to the cab or the car. But, it seems both actuators are moving and opening the main vents. So now I have no idea what it could be. Unless there are other actuators that may be holding the air from the drivers area? Any idea which direction i should head?

How long has your 2009 Mercedes-Benz C350 had this problem?

Its been like this for about 10 months.
