Detailed Description

This HVAC heater blend door actuator is designed for specific Buick, Chevrolet, and GMC models from 2013 through 2017. It helps move the blend door inside the HVAC case so the system can direct air for temperature control, mode selection, or outside air operation depending on the vehicle configuration. If your Buick Enclave, Chevrolet Traverse, or GMC Acadia has inconsistent cabin temperature or air distribution, this actuator is the direct replacement part to verify against the original unit.

Part number 604-924 is listed for multiple OE-style interchange references and is intended for vehicles requiring the same rotary actuator design. The fitment includes main and auxiliary locations across the supported GM platforms, making it important to match the original position and HVAC function before ordering.

Common Problems This Part Can Address

Incorrect cabin temperature control
Airflow stuck on one vent position
HVAC blend door movement failure
Loss of outside air or mode selection control
Clicking or non-responsive HVAC actuator operation

Installation Notes and Tips

Verify the original actuator’s position, connector style, and HVAC function before installation. Access is typically through the HVAC housing, so compare the removed part to Dorman 604-924 before final assembly. After installation, cycle the ignition and HVAC controls to confirm proper temperature and mode response.

Quality Assurance

Dorman designs this replacement actuator to match the quality and performance of the original blend door actuator on the listed applications. It is built for direct-fit service on the specified Buick Enclave, Chevrolet Traverse, and GMC Acadia platforms.

This part fits 56 vehicles
