Manufactured to strict Mopar specifications, this direct-fit actuator offers precise calibration, factory electrical compatibility, and long-term durability. Unlike lower-quality aftermarket replacements, genuine Mopar HVAC components provide proper fitment and reliable operation under extreme temperature conditions.
This actuator is commonly referred to as an A/C temperature door actuator, HVAC heater blend door actuator, or temperature control servo motor. It is a critical component in maintaining proper climate control functionality in second-generation Dodge Ram trucks.
