Description
Heater servo motor for Citroën and Peugeot vehicles. You may receive a direct replacement. Air conditioning gearmotor.
The Valeo heater servo motor is a direct-fit replacement part designed to restore accurate control of HVAC flaps and temperature blending on a range of Citroën and Peugeot models. Built as a compact motor with an integrated reduction gearbox, this unit drives the internal doors and flaps in the climate unit to regulate airflow distribution and cabin temperature. Ideal for professional garages and experienced DIYers, the part matches common OEM mounting points and electrical connections to simplify replacement and get the system operating again quickly.

Function
This servo motor (motoreductor) actuates the heater/air‑conditioning flaps (blend doors and distribution flaps) inside the HVAC housing. By moving internal gears and linkages it controls the mix of hot and cold air and directs flow to windscreen, face or footwell outlets. Proper operation is essential for accurate cabin temperature regulation and defogging performance.
Compatibility
Designed for selected Citroën and Peugeot climate units. Commonly fitted to Citroën C2, C3 and C4 II platforms and Peugeot 308 applications. Check the product codes listed above against the broken unit to confirm match.
Replacement Procedure
Replacement typically requires access to the HVAC unit behind the dashboard (glovebox or lower dash trim removal may be necessary). General steps:
- Disconnect the negative battery terminal before starting work.
- Remove relevant trim panels or glovebox to reach the climate unit.
- Unplug the electrical connector from the servo motor and remove fixing screws.
- Extract the old servo, transfer any linkages as needed and fit the new unit in the correct position.
- Reconnect the electrical connector, reassemble trims and reconnect the battery.
- Cycle the HVAC controls through full range to confirm movement; some vehicles perform automatic calibration on first use.
Installation Recommendations
- Always Disconnect The Battery Before Demounting To Avoid Short Circuits And Prevent Damage To The Unit.
- Inspect Linkages And Flap Mechanisms For Physical Damage Or Obstructions Before Installing The New Servo.
- Handle The Unit Carefully To Avoid Damaging Plastic Gear Teeth Or The Electrical Connector.
- If The HVAC System Requires Calibration After Replacement, Follow Manufacturer Procedures Or Use Diagnostic Equipment Where Available.
Most Common Failure Causes
Servo motors of this type commonly fail due to mechanical wear or plastic gear damage inside the reduction gearbox. Symptoms include intermittent or stuck flaps, unusual noises (grinding or clicking) from the dashboard area, incorrect temperature mixing or loss of airflow direction control. Other causes are moisture ingress, debris jamming the mechanism, worn motor brushes or seized bearings. Failure usually appears after extended service life or when internal gears strip under load.
Why Choose This Part
Provides a cost‑effective way to restore HVAC function without replacing the whole climate unit. The part offers direct compatibility with common mounting and electrical interfaces used on affected Citroën and Peugeot models, making it a practical choice for repair shops and competent DIY mechanics looking to return full heating and ventilation control to the vehicle.
