Description
Product Overview
The Behr heater servo motor is a direct-fit HVAC actuator designed for Citroën & Peugeot vehicles. It precisely controls the blend and air-distribution flaps to maintain set cabin temperature and airflow. Ideal for professional mechanics and DIY enthusiasts who commonly search by part number.
Key Benefits
- Direct-fit replacement for PSA heater control systems.
- Restores accurate temperature control and airflow distribution.
- Easy identification by well-known part numbers for faster servicing.
Compatibility
Suitable for selected PSA models, commonly fitted to Citroën small models such as C2 and C3 and equivalent Peugeot small cars. Always verify the part number against the vehicle’s VIN or service manual before ordering.
How It Works
The servo motor is a 12V electrical actuator that moves HVAC flaps inside the heating and ventilation unit. It converts electronic signals from the climate control module into precise mechanical movement of blend and mode doors, ensuring the cabin reaches and maintains the desired temperature and airflow pattern.
Fault Symptoms & Causes
- Little or no change in cabin temperature when adjusting controls.
- Unusual clicking or grinding noises from behind the glovebox or dashboard (indicating worn or stripped gears).
- Incorrect or stuck airflow direction.
- Common causes include internal gear wear, motor burnout, moisture ingress or connector/electrical faults.
Replacement & Installation
Replacement is straightforward for competent technicians: disconnect the battery, remove the glovebox or lower dashboard trim to access the HVAC unit, unplug the electrical connector, remove retaining screws, replace the actuator and reassemble. Some vehicles may require calibration or a reset procedure; consult the manufacturer’s repair instructions or a factory service manual.
