Detailed Product Overview

This HVAC blend door actuator is used in the climate control system to move the blend door and regulate airflow direction and cabin temperature. On 2005-2015 Nissan Armada and 2005-2015 Nissan TITAN applications, it supports outside-air related HVAC operation where listed. On 2007-2010 INFINITI QX56 applications, it covers temperature, mode, and left or right main positions as specified by fitment.

For buyers searching for a Nissan Armada blend door actuator, Nissan TITAN HVAC actuator, or INFINITI QX56 temperature control actuator, Dorman 604-624 provides a direct replacement option for the listed factory applications. The part number 604-624 is also referenced in OE-style replacement searches for these vehicles.

Common Symptoms This Part Can Address
