Dorman 604-339 HVAC Blend Door Actuator - Left Main, Main or Right Main
Dorman 604-339 HVAC Blend Door Actuator
Dorman 604-339 is a direct replacement HVAC blend door actuator for select Volkswagen and Audi applications. It is built to restore proper air door movement so the cabin can switch between temperature settings as intended. This part number 604-339 is used on multiple positions, so verifying the exact actuator location is important before ordering.
Key Features
- Direct replacement air door actuator for specific HVAC blend door applications
- Black plastic body and black connector for a factory-style fit
- Rotary activation type with 5 terminals and female connector design
- 3 mounting holes for secure installation
- Compact dimensions: 3.34 in. length, 2.275 in. width, 1.22 in. height
- No actuator arm included
- Cross-references Four Seasons 73344 for the same application
Detailed Description
Dorman 604-339 is an HVAC blend door actuator designed to replace the original unit on select Audi A3, Audi A3 Quattro, Audi Q2, Audi Q2 Quattro, Volkswagen Atlas, Volkswagen e-Golf, Volkswagen Golf, Volkswagen Golf SportWagen, Volkswagen Taos, Volkswagen Tiguan, and Volkswagen Teramont models. This actuator helps control the blend door position inside the HVAC system, which affects how air is directed and mixed for cabin temperature control. The part number 604-339 is also referenced by Standard Ignition ADR4381 and interchange numbers 2Q0907511G, 5Q0907511K, ADA571, and DA1406.
Because many vehicles use more than one air door actuator, position and function matter. Review the application notes carefully to confirm whether your vehicle needs the main, left main, or right main actuator before installation. For example, this part fits 2022-2023 Volkswagen Taos, right main; 2020-2023 Volkswagen Tiguan, right main; 2018-2019 Volkswagen Atlas, left main; and 2013-2017 Audi A3, main.
What It Helps Fix
- Incorrect cabin temperature control
- Airflow stuck on one temperature setting
- HVAC doors that do not respond properly to control inputs
- Uneven heating or cooling from a failed blend door actuator
- Noise or erratic movement from a worn actuator
Installation Notes and Tips
Confirm the actuator position and function before replacement, since the same vehicle may use multiple HVAC actuators. This unit uses a rotary switch activation type, a female connector, and 5 terminals. No mounting hardware is listed, so reuse the existing fasteners if service procedures call for it. If you are unsure which actuator position your vehicle uses, consult a qualified service technician.
Quality Assurance
Dorman designs this air door actuator as a direct replacement for the original component on the listed applications, with fitment coverage for 2013-2023 Audi and Volkswagen models. The part is built to match the required position and function for the specified HVAC systems.
