This replacement unit (part numbers 604-112, 1573952, 89018374, 604112, 15-73952) is engineered as a durable, plug-and-play swap for many 2003–2014 model-year GM trucks and SUVs. It reinstates motorized control over the HVAC blend door so your cabin temperature and venting respond reliably to the controls.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this actuator improve my cabin temperature control?\u003c\/h3\u003e\n\u003cp\u003eReplacing a failing actuator returns precise movement to the blend door, allowing the HVAC system to properly mix warm and cold air. That means the temperature you set on the dash will be the temperature felt at the vents, rather than inconsistent or shifting airflow.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRestores accurate blend-door positioning for consistent temperature output.\u003c\/li\u003e\n  \u003cli\u003eEliminates delayed or jerky vent response caused by worn gears or motor.\u003c\/li\u003e\n  \u003cli\u003eMatches original electrical connector for straightforward swap.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich vehicles is this part compatible with?\u003c\/h3\u003e\n\u003cp\u003eThis GOOACC actuator fits a broad list of GM vehicles across model years primarily between 2003 and 2014.
