Description
High-quality Valeo Heater Servo Motor designed for PSA vehicles, specifically Citroën C4 II and Peugeot 308. This electric servo (blend-door) actuator controls the internal HVAC flaps to regulate airflow and cabin temperature, helping maintain passenger comfort and reliable climate control performance.
Key Features
- Direct-fit replacement for Valeo part numbers T1002120V and 6479E7.
- Restores precise temperature regulation by accurately positioning the heater/ventilation flaps.
- Robust electric motor and gear assembly built for automotive HVAC duty cycles.
- Ideal for professional mechanics and experienced DIY installers.
How It Works
The servo motor operates the blend door or flap inside the heater box. By rotating a small output shaft it changes the path of airflow through the heater core and vents, allowing the HVAC system to mix warm and cool air to reach the selected cabin temperature. The actuator receives position commands from the vehicle’s climate control unit and feeds back its position to ensure accurate control.
Symptoms Of Failure And Common Causes
Typical signs that the heater servo motor is failing include inconsistent cabin temperature, inability to change vent positions, repeated clicking noises from the dashboard area, or a loss of responsiveness from the HVAC controls. Failures are commonly caused by worn or stripped plastic gears, moisture ingress, heat-related degradation, or electrical/connector faults.
Replacement And Installation Notes
Replacement is straightforward for technicians and skilled DIYers. Basic procedure: disconnect the negative battery terminal, remove necessary dash panels or glovebox to access the heater box, unplug the servo connector, remove retaining screws, swap the actuator and reassemble. Typical tools required: Torx or Phillips drivers, small sockets, panel trim tools. After installation, verify actuator movement and climate control operation. If unsure, consult the vehicle service manual for exact removal steps and safety precautions.
