What is the reason why the middle two vents of the Audi A3 air conditioner are not blowing air?

Audi A3 is a four-cylinder. The following is an introduction to the Audi A3: 1. Introduction: The Audi A3 is a sedan product produced by Audi, developed based on the Volkswagen MQB platform. The body features lightweight design and aluminum materials, and is powered by multiple engines including 1.4TFSI and 1.8TFSI. 2. Features: ESP system, direct gasoline injection FSI six-cylinder engine. The high-torque TDI technology of the injector, combined with the DSG shift-change transmission and clutch, 5-speed and 6-speed automatic transmissions, and a new tiptronic automatic transmission, as well as four-wheel drive options.
The other day when I was driving my friend's Audi A3, I also encountered the issue of no air coming from the center vents. After struggling for a while, I finally figured out the problem. This kind of issue is most likely caused by a stuck or broken air conditioning flap motor, which controls the movement of the air direction flaps. It could also be due to a detached or leaking air duct, such as a cracked plastic pipe joint from aging. You can first try switching the air blowing modes, like changing from the windshield to face mode and then to foot mode, and listen for any 'clicking' sounds inside the dashboard. If there's no sound at all, it's probably the flap motor that's gone. Remember, never force the vent blades—precision parts like those in Audis are much more expensive to repair compared to Japanese cars. Last time I replaced this motor, it cost me over 800 yuan.
Last time I helped my daughter check her A3, the center vents weren't blowing air either. These dual-zone climate systems in German cars can be quite finicky - when left and right temperatures are set differently, the center airflow automatically adjusts to balance, but sometimes accidentally hitting the SYNC button locks synchronization and messes things up. First check if the climate control screen shows a sync lock symbol, or try setting both driver and passenger temperatures to LO. If that doesn't work, it might be a faulty air blend door actuator. This little box sits behind the glove compartment - German cars love using plastic gears that tend to crack with winter temperature fluctuations.
Having run an auto repair shop for twenty years, I've dealt with numerous Audi AC issues. When both center vents stop working simultaneously, it's almost always due to a completely blocked central air duct—especially common right after maintenance when apprentices often drop rags deep into the dashboard, jamming the flaps. Here's a lesser-known fact: Audi AC units have foam seals inside that can crumble with age and get sucked onto the filter. Focus your inspection on the blend door behind the glovebox. If you can feel faint airflow by placing your palm over the vent, this is likely the culprit.
