Dorman 604-323 HVAC Blend Door Actuator - Main

Dorman 604-323 HVAC Blend Door Actuator

Dorman 604-323 is a rotary HVAC blend door actuator built for specific Hyundai and Kia applications that use blade terminals and a 5-terminal female connection. It is engineered to match the function and performance of the original heater blend door actuator for mode selection in the vehicle HVAC system.

Key Features

• Rotary switch activation type for HVAC mode control
• Blade terminals with 5-terminal female connector
• Plastic housing for direct replacement use
• OE-style replacement for the original blend door actuator
• Cross-reference: Hyundai/Kia 971542E200 for the same application

Detailed Description

This HVAC blend door actuator, part number 604-323, is used in the climate control system to move the air door for mode selection. It is a direct-fit replacement for select 2005-2009 Hyundai Tucson and 2005-2009 Kia Sportage models, plus 2010 Kia Sportage vehicles built through 1/26/10. If you are searching for a Dorman 604-323 HVAC blend door actuator for a Hyundai Tucson or Kia Sportage, this part matches the original actuator style and connection layout used in those applications.

Because the actuator controls air distribution inside the HVAC case, correct operation is important for directing airflow to the vents, floor, or defrost outlets. The Dorman 604-323 is built to align with the original part’s electrical and mechanical design so it can restore normal HVAC mode function on the listed vehicles.

What It Helps Fix

• HVAC air not switching between panel, floor, and defrost modes
• Stuck or inconsistent vent direction control
• Clicking or repeated movement from a worn actuator
• Loss of proper heater and A/C airflow routing
• Faults related to a failed blend door actuator in the HVAC system

Installation Notes and Tips

Verify the connector style, terminal count, and vehicle build date before installation. This part uses a rotary activation design with blade terminals and a female 5-terminal connection, so matching the original unit is important for proper operation. On 2010 Kia Sportage applications, confirm the vehicle was built on or before 1/26/10. After installation, cycle the HVAC controls to confirm the mode door responds correctly.

Quality Assurance

Dorman designs this HVAC heater blend door actuator as a precision-engineered replacement for the original component on the listed vehicles. It is intended to provide the same basic fit and function expected from the OE-style actuator in the HVAC system.
