Dorman - OE Solutions HVAC Blend Door Actuator P/N:604-943
When your climate control stops directing air the way it should, the Dorman blend door actuator 604-970 is the electric motor-and-gear unit that repositions an HVAC air door to route and mix cabin airflow. It installs as a direct-fit replacement for the 2004-2010 Infiniti QX56, 2005-2015 Nissan Armada, 2004 Nissan Pathfinder Armada, 2004-2009 Nissan Quest and 2004-2015 Nissan Titan. Dorman lists this as a rear air door actuator (catalog positions: MAIN and AUXILIARY) — see the Buyer's Guide tab for engine-level fitment.
Signs the original actuator may need replacing include clicking or knocking noises from behind the dash, air that won't switch between vents, or a blend door stuck on one temperature. If a failed actuator is the cause, this unit replaces it. If you're unsure which position you need, consult a qualified service technician.
