Mopar 05104879AA A/C Temperature Door Actuator Blend Door Servo

The Mopar 05104879AA is a genuine OEM A/C temperature door actuator, also known as a blend door servo or electric motor, designed as a direct-fit replacement for Dodge and Jeep vehicles. This component is a known common failure point in the HVAC system and is responsible for controlling the position of the temperature blend door, which regulates the mix of heated and cooled air delivered to the cabin.

When this actuator fails, the HVAC system may become stuck at a single temperature or lose temperature control entirely, making it one of the most straightforward components to diagnose and replace when climate control performance is compromised.
