Description
Product Overview
Valeo heater servo motor (also known as HVAC actuator) designed for selected Citroen and Peugeot models. This unit carries product codes N100462G and 6447NQ (additional cross-reference: 0801071C, 1201051C). It is a used part that has been previously inspected and is offered for reliable replacement of a failing heating/ventilation actuator. Suitable for professional workshops and competent DIY enthusiasts looking for a cost-effective spare part.
Compatibility
Commonly fitted to Citroen C2 and C3 models and compatible with certain Peugeot vehicles such as the 1007. Compatibility should always be confirmed by matching the vehicle application and the product codes printed on the part (N100462G, 6447NQ, 0801071C, 1201051C).
Function And Common Failures
The heater servo motor controls air distribution and blend functions inside the HVAC box, moving doors and flaps to direct warm or cold air to the chosen vents. Typical failure symptoms include unusual clicking or grinding noises from the dashboard, incorrect air distribution (e.g., stuck on defrost or face vents), inconsistent cabin temperature, or a non-responsive climate control setting. Failures are most often caused by worn electrical motor windings, broken or stripped plastic gears, mechanical jamming of the blend/air doors, or moisture ingress into the actuator.
Installation Notes
Replacement is straightforward for a trained technician but requires some disassembly of the dashboard or glovebox area to access the heater box, depending on the model. Typical steps:
- Disconnect the negative battery terminal before starting.
- Remove necessary trim panels or the glovebox to reach the HVAC housing.
- Unplug the electrical connector from the servo motor and remove the mounting screws or clips.
- Extract the old actuator, transfer any needed linkage or position marks, and fit the replacement unit.
- Refit all panels, reconnect the battery and test the HVAC functions through full range to confirm correct operation.
Careful handling of plastic gears and HVAC flaps is important to avoid additional damage. If in doubt, refer to a vehicle-specific repair manual or contact a professional mechanic.
Maintenance And Expected Lifetime
Lifetime varies with vehicle usage and environmental conditions. Actuators commonly last many years but can fail sooner in vehicles exposed to moisture, dust, or extreme temperature cycling. Inspect servo motors if you observe irregular HVAC performance or noisy operation. Replacing a failing actuator restores proper air distribution and prevents further wear on related HVAC components.
