HVAC Blend Door Actuator for Auxiliary Climate Control

Dorman 604-141 is a rotary HVAC blend door actuator built to match the quality and performance of the original unit on specific vehicles. It is used in auxiliary HVAC systems to control mode selection and temperature blending, helping restore proper cabin air distribution and temperature control.

Compatible With 2007-2012 GMC Acadia, auxiliary; 2008-2012 Buick Enclave, auxiliary; 2009-2012 Chevrolet Traverse, auxiliary; and 2007-2010 Saturn Outlook, auxiliary. This Dorman 604-141 replacement is a direct-fit service part for the listed applications.

Key Features

  • Rotary switch activation type for auxiliary HVAC control
  • Plastic housing for OE-style fit and function
  • Precision-engineered to match original actuator performance
  • Used for mode selection and temperature blend control
  • Packaged as actuator only

Detailed Product Overview

This HVAC heater blend door actuator is designed for vehicles that use an auxiliary climate control actuator to move the blend door between air distribution and temperature positions. Dorman 604-141 is engineered to replicate the operation of the original actuator on the specified Buick Enclave, Chevrolet Traverse, GMC Acadia, and Saturn Outlook applications. If your system is showing inconsistent airflow direction or temperature response, this part addresses the actuator that drives those internal HVAC door movements.

This part cross-references Four Seasons 73021 for the same application.

Common Issues This Part Can Help Resolve

  • Airflow stuck on one vent or mode setting
  • Inconsistent cabin temperature control from the auxiliary HVAC system
  • Clicking or repeated movement from a failing blend door actuator
  • Loss of response when changing HVAC settings
  • Improper air distribution in the rear or auxiliary climate zone

Installation Notes and Tips

Verify the vehicle year, make, model, and auxiliary HVAC position before installation. Compare the connector, mounting points, and actuator style to the original unit to confirm Dorman 604-141 is the correct replacement. After installation, cycle the HVAC controls to allow the system to relearn actuator positions if required by the vehicle.

Quality Assurance

Dorman designs this actuator as an OE-style replacement for specific factory applications, with construction and operation matched to the original blend door actuator used in the listed vehicles.
