A-NAFTULY’s unit is designed to match factory fit and function while using upgraded ABS housing and modern internal circuitry for longer service life. It installs without modification and replaces OE numbers 1573952, 89018374, 604-112, 604112, and 15-73952.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this actuator fix inconsistent cabin temperatures?\u003c\/h3\u003e\n\u003cp\u003eThe blend door actuator moves the internal flaps that direct air across the heater core or evaporator, letting the HVAC mix warm and cool air to reach your set temperature.
