Description
Product Overview
This BEHR heater servo motor is a direct-fit HVAC actuator for selected Citroën and Peugeot models. Designed to control heater/flap movement and air-mixing functions, it restores precise cabin temperature regulation and distribution. The unit is suitable for professional mechanics and competent DIY enthusiasts who replace faulty HVAC actuators using the vehicle part number for verification.
Application And Compatibility
Common fitment includes various PSA platforms such as Peugeot 406 and 607, and Citroën C5 I and Xsara. Always verify fitment by matching the vehicle VIN or existing part number to ensure correct application. Product codes listed below help confirm compatibility.
Function And Symptoms Of Failure
The servo motor operates the heater blend and distribution flaps inside the dashboard to regulate cabin temperature and airflow direction. Typical symptoms of a failing actuator include inconsistent cabin temperature, clicking or grinding noises from behind the dash, stuck or non-responsive vents, and loss of automatic temperature control. Failures are commonly caused by worn or stripped plastic gears, motor burnout, moisture ingress, or connector/cable corrosion.
Replacement And Installation Notes
Replacement generally requires removal of lower dash panels or the glovebox to access the actuator. Recommended steps: disconnect the negative battery terminal, remove necessary trim panels, unplug the electrical connector, unfasten the actuator retaining screws or clips, swap the unit, then reassemble. After installation, cycle the HVAC controls and check full range travel of flaps; some systems self-calibrate on ventilation cycles, while others may require manual calibration via control module procedures. Work carefully to avoid damaging fragile plastic gears and linkages.
Durability And Service Life
Service life depends on use and environment; typical lifespan ranges from several years up to a decade or more under normal conditions. Repeated forceful obstructions, water intrusion, or defective linkages accelerate wear. Replacing a failing actuator restores smooth, quiet operation and prevents overworking related HVAC components.
