    Air does not flow from the center vents. MB dealer said it was the air-conditioning actuator, which needs to be replaced. They said it is a $600 to $800 repair at the dealership and could be fixed for much less at an independent shop (recommended that due to the car's age and value, especially since its not a critical safety system).
