Detailed Product Description

Four Seasons 73344 is an HVAC recirculation door actuator that helps move the air door inside the climate control housing. In vehicles such as the Audi A3, Audi Q3, Volkswagen Golf GTI, and Volkswagen Tiguan, this type of actuator is responsible for directing airflow for defrost operation and cabin air recirculation. The gear linkage design supports controlled door positioning, while the 5-pin electrical interface matches the listed vehicle configurations.

This part cross-references A60344 and 2Q0907511G for the same application. If you are replacing a failed HVAC air door actuator on a Volkswagen Atlas Cross Sport, Audi S3, or Volkswagen Jetta, verify the position and climate-control notes before installation. The Four Seasons 73344 is listed across model years from 2015 through 2024, with fitment varying by vehicle, position, and HVAC equipment.

What It Can Help Resolve

• Stuck or inoperative recirculation door movement
• Defrost airflow that does not route correctly
• HVAC doors that click, bind, or fail to respond
• Temperature or airflow distribution issues tied to actuator failure
• Climate control performance problems on select Audi and Volkswagen vehicles

Installation Notes and Tips

Confirm the exact vehicle, model year, position, and HVAC configuration before ordering. This part is listed for N/A, Left, and Right positions depending on application, including defrost and rear AC-related fitments. For example, it fits 2023-2024 Audi A3, N/A, Defrost; fits 2022-2024 Volkswagen Taos, Right, w/ ATC (Automatic Temperature Control); and fits 2022-2024 Volkswagen Golf R, Left, Vehicle w/ Rear AC.

After installation, cycle the climate control system to verify door movement and proper airflow routing. If the HVAC system has stored fault codes or calibration requirements, follow the vehicle service procedure for actuator initialization.

Quality Assurance

Four Seasons HVAC components are cataloged for direct replacement use in listed vehicle applications. This part is identified by part number 73344 and is supported by the fitment data provided for Audi and Volkswagen models from 2015-2024.
