Description
BEHR heater servomotor for Citroën C5 X7 and Peugeot 407 facelift.
Replace a worn or failed heater servomotor with this BEHR unit designed for Stellantis models. The actuator controls HVAC flaps and temperature blend doors to ensure accurate cabin heating and ventilation. Designed for professional workshops and competent DIY mechanics, this part restores correct climate control operation, eliminates abnormal noises from the dashboard, and prevents inconsistent cabin temperatures. Customers frequently search by product code, so this listing includes common reference numbers to simplify finding the correct replacement.
Technical Information
- Manufacturer: BEHR

- Additional Numbers: b 42; 647947
Function And Fitment
The servomotor operates the HVAC unit’s internal flaps (blend/air distribution), converting electrical commands from the climate control module into precise flap movement. Correct operation is essential for temperature regulation, defrosting, and balanced air distribution. This unit is intended as a direct replacement for the listed models and fits the OEM-style mounting and electrical connector used on the Citroën C5 X7 and Peugeot 407 facelift HVAC assemblies.
Installation Recommendations
Before starting, disconnect the negative battery terminal to avoid short circuits. Access is usually from the passenger side behind the glovebox or through the lower dash panel; the actuator is mounted on the HVAC housing. Remove the retaining screws, unplug the electrical connector, and replace the actuator without forcing the flap linkage. After installation, reconnect the battery and run the climate control through a full cycle to verify smooth movement and proper temperature response. If available, perform actuator calibration or follow the vehicle manufacturer’s climate control reset procedure to ensure correct end stops and position feedback.
Why This Part Most Often Fails
Most failures are caused by worn plastic gears, internal motor burnout, or contamination. Moisture ingress and debris in the HVAC housing can accelerate wear or seize the flap linkage. Symptoms include grinding or clicking noises, inability to change temperature or air distribution, and erratic movement. Replacing the actuator at the first signs of malfunction prevents further stress on the HVAC mechanism and avoids downstream issues like stuck flaps or blower overload.
