Description
Product Overview
This Valeo heater servo motor (actuator) controls the HVAC flaps responsible for air distribution and temperature blend in PSA vehicles. Supplied under codes 653118V.C and 07 6447EL, it is commonly used on Citroën and Peugeot models and is often searched by its product number.
Compatibility
Fits vehicle models: Citroën Xsara, Citroën C5 I (first generation), Peugeot 406 and Peugeot 607. Always verify compatibility by comparing the product code with the original part on your vehicle before ordering.
Function
The servo motor moves internal heater and ventilation flaps to regulate airflow direction and temperature mixing. Accurate flap movement is essential for correct cabin heating, air distribution and climate control response.
Signs Of Failure
Common symptoms of a failing servo motor include unusual grinding or clicking noises from the dash, incorrect temperature mix (stuck hot or cold), air directed to wrong vents, intermittent HVAC operation or fault indications on the climate control system.
Why It Fails & Typical Lifespan
Failures are usually caused by worn internal gears (often plastic), electrical connector corrosion, seized shafts or moisture ingress. Lifespan varies with use and vehicle age; failures are more common after several years of service, typically from about 8 to 15 years depending on conditions.
Replacement & Fitment Notes
Replacement is usually straightforward for a trained mechanic or an experienced DIYer. Typical steps: disconnect the battery, remove the glovebox or lower dashboard trim to access the heater box, unplug the electrical connector, remove mounting screws, fit the new actuator and test function before reassembly. Keep position marks or note flap positions to avoid misalignment.
Installation Tips
Handle the actuator gear teeth carefully and avoid forcing the flaps. Test full travel of the actuator with the ignition on before final reassembly. If the original part shows broken gears or heavy corrosion, inspect the heater box and linkages for additional damage.
