The cessation of airflow from the central air vents occurred some weeks ago, and the cause remains unknown to me. The air conditioning system works well, as does the heating system. The lateral ventilation outlets function adequately. When the red button on the vents is pressed, warm air is emitted from both the top and side vents. Conversely, pressing the blue button causes the top and side vents to release cold air. The symbols shown on the screen only indicate the direction of airflow towards the front and footwell areas, rather than the screen itself. However, despite this indication, air continues to be emitted from the screen vents. There seems to be a malfunction in the mechanism responsible for diverting airflow between the screen and central vents.
While the issue at hand is not of significant magnitude, I am curious whether there exist any expeditious and straightforward procedures that I might do to assess the situation. The diagnostics on the climate control panel were conducted, however, no fault codes were detected.
