Restore precise HVAC airflow control with the Dorman blend door actuator (P/N 604-624, also written 604624), a direct-fit replacement for the 2007-2010 Infiniti QX56, 2005-2015 Nissan Armada, and 2005-2015 Nissan Titan. This small electric motor drives a door inside the HVAC case to direct air; Dorman lists it as an Air Inlet air door actuator covering the MAIN, RIGHT MAIN, and LEFT MAIN positions, so it's the Dorman air door actuator many owners search for by name.

  • Direct replacement: engineered to install like the original air door actuator on the listed applications.
  • Position specific: vehicles often use several HVAC door actuators, so review this part's application notes to confirm it matches the location and function of the one you're replacing.
  • Durable construction: designed and tested to strict standards to help resist wear and electrical burnout for reliable operation and long service.
  • Trustworthy quality: backed by a team of experts and engineers in the United States with more than a century of experience.

If a failed blend/air door actuator is behind a clicking noise behind the dash or airflow that won't move as commanded, replacing it with this Dorman heater blend door actuator addresses that worn unit. Diagnose the cause before ordering.

Frequently Asked Questions

Does this Dorman hvac heater blend door actuator fit my Nissan Titan?

Yes — it's listed for the 2005-2015 Nissan Titan, plus the 2005-2015 Nissan Armada and 2007-2010 Infiniti QX56. Because a vehicle can use several actuators, confirm the position against the application notes.

What does an HVAC air door actuator do?

It's a small electric motor that moves a door inside the HVAC case to control airflow — here the air inlet — so the system delivers the airflow you select at the controls.

What are signs this actuator may need replacing?

Common signs include a clicking or knocking noise behind the dash, or airflow that won't change as commanded. These can have other causes, so diagnose before replacing.

Which position does the Dorman blend door actuator 604 cover?

Dorman lists P/N 604-624 for the MAIN, RIGHT MAIN, and LEFT MAIN positions. Since a vehicle may have multiple actuators, verify it matches the one you need to replace.

What other part numbers does this Dorman air door actuator replace?

It cross-references APBDA0239, DA1262, 27443ZH00A, 27743ZH00A, and ADR273.
