Dorman's 604-970 is a position-specific, direct-replacement actuator designed to match the original fit and function for certain model years of Infiniti QX56 and multiple Nissan models including Armada, Quest, Titan and Pathfinder Armada. Before ordering, confirm the actuator position and vehicle compatibility using your vehicle trim in the garage or fitment tool.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this actuator fix noise or inconsistent airflow?\u003c\/h3\u003e\n\u003cp\u003eWorn or failed blend door actuators often produce repeated clicking noises and fail to move internal HVAC doors, causing inconsistent cabin temperature or wrong vent selection. Replacing the actuator with the correct position-specific unit restores the actuator’s ability to move the blend\/air door and reliably control airflow paths.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eEliminates clicking and grinding noises from dash HVAC area\u003c\/li\u003e\n  \u003cli\u003eRestores accurate air temperature mixing between vents\u003c\/li\u003e\n  \u003cli\u003eReturns control over vent selection and airflow direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich vehicles and years does the Dorman 604-970 fit?\u003c\/h3\u003e\n\u003cp\u003eThe 604-970 is listed for specific model years and positions—compatibility depends on year, model and the actuator’s function in the HVAC system.
