Description
Product Overview
Valeo HVAC servo motor (heater/air conditioning blend door actuator) compatible with Citroën and Peugeot vehicles. This used unit, supplied with verified origin and previous testing, offers a cost-effective replacement for faulty heater/AC actuators on models such as Citroën C2, C3 and some Peugeot models including 1007. Common part numbers are N100462G and 6447NQ, making it easy to search by reference.
Function And Common Symptoms
The servo motor controls the blend door or airflow flaps inside the HVAC unit to route hot or cold air as requested by the climate controls. Typical failure symptoms include inconsistent cabin temperature, inability to change airflow direction, audible clicking or grinding noises from behind the dashboard, or complete loss of actuator movement. Replacing a faulty actuator restores proper airflow distribution and climate control responsiveness.
Compatibility And Fitment Advice
While this Valeo servo is listed for Citroën C2 and C3 and Peugeot 1007, fitment can vary by production date and regional variant. Always verify the part number on your existing actuator before ordering. Cross-reference codes N100462G, 6447NQ, 0801071C and 1201051C to confirm compatibility with your vehicle.
Installation Guide (General)
Removal and replacement are straightforward for a competent mechanic or experienced DIYer. Typical steps:
- Disconnect the negative battery terminal to prevent short circuits.
- Access the actuator by removing the glovebox or lower dash panels, depending on model.
- Unplug the electrical connector and remove the mounting screws securing the servo to the HVAC housing.
- Install the replacement servo, reattach screws and connector, reassemble trim and reconnect the battery.
- Cycle the climate controls and check for proper operation. Some vehicles may require an HVAC relearn or calibration procedure as per manufacturer instructions.
Replacement Interval And Failure Causes
There is no fixed interval for actuator replacement; typical triggers are wear of internal gears, moisture ingress, dust contamination, or electrical motor failure. Older vehicles and high-mileage cars are more prone to actuator wear. Timely replacement prevents further HVAC damage and restores cabin comfort.
