Product Description
Mopar 04720279AB Heater Actuator for 1994-2002 Dodge Ram 2500 & 3500
The Mopar 04720279AB Heater Actuator is a genuine OEM HVAC component designed to restore proper heater and climate control operation in 1994-2002 Dodge Ram 2500 and 3500 trucks. Engineered to factory specifications, this actuator controls heater door and vent/defrost door movement, allowing accurate temperature regulation and proper airflow distribution throughout the cabin.
Over time, factory heater actuators can fail due to worn internal gears, diaphragm issues, electrical motor failure, or age-related wear. Common symptoms include clicking noises behind the dash, incorrect air temperature, stuck blend doors, poor airflow control, or inconsistent heater performance. Replacing a failed actuator with a genuine Mopar component helps restore factory HVAC functionality and long-term reliability.
Unlike many aftermarket alternatives, the Mopar 04720279AB Heater Actuator is manufactured to OEM standards for proper fitment, performance, and durability in both daily-driven and heavy-duty work truck applications.
