Compatibility
- Citroën Xsara
- Citroën C5 I
- Peugeot 406
- Other PSA models using references 0132801169 or 6447HL (verify fitment by part number before installation).
When And Why It Fails
Heater servo motors commonly fail due to mechanical wear of plastic gears, accumulated debris restricting flap movement, electrical faults in the motor or potentiometer, or connector corrosion from moisture. Symptoms include no airflow change when adjusting temperature or vent mode, unusual clicking noises behind the dash, or stuck flaps causing incorrect cabin heating or cooling.
Replacement And Installation
Replacement is a routine task for trained mechanics and experienced DIYers. Typical steps:
- Remove necessary trim panels or glovebox to access the HVAC unit (vehicles vary—consult a repair manual for model-specific instructions).
- Disconnect the electrical connector and remove mounting screws securing the actuator.
- Withdraw the old servo motor, transfer any required linkage or mounting plate if applicable, and fit the new unit in the correct orientation.
- Reconnect the connector and test operation through all modes; some systems require a calibration step or ignition cycle to re-initialize the actuator position.
Recommended tools: trim tools, Torx or Phillips drivers depending on vehicle, and a multimeter for electrical checks. Disconnecting the battery is optional but recommended when working on electrical components.
Maintenance And Longevity
Service life depends on usage and environment. Regular inspection of HVAC operation and prompt replacement at early signs of failure prevents prolonged cabin discomfort. Avoid forcing manual flap movement to reduce risk of gear damage.
