Description
Heater servo motor for Citroën C2, C3, Xsara Picasso and Peugeot 206 and 307
Product Overview
Replacement heater servo motor (HVAC actuator) designed for selected Citroën and Peugeot models. This compact electric motor drives the HVAC flaps inside the heater box to control airflow direction and temperature blend. Built to fit the original mounting points and electrical connector, it restores precise flap movement and improves cabin heating and ventilation control.
Key Benefits
- Direct fit for easy replacement on compatible Citroën and Peugeot models.
- Restores accurate flap and blend control for consistent cabin temperature.
- Suitable for mechanics and competent DIY installers familiar with dash removal.
- Searchable by OEM/Product code for fast identification: 95494 / 6447QN.
Typical Applications
Intended for use in the following vehicles:
- Citroën C2
- Citroën C3
- Citroën C3 Pluriel
- Citroën Xsara Picasso
- Peugeot 206
- Peugeot 307
How The Part Works
The heater servo motor is an electric actuator that moves internal HVAC flaps (mode, recirculation or temperature blend doors) via a small gearbox and position feedback (often a potentiometer or end stops). Correct operation ensures that air is directed to the selected vents and that temperature blends respond to user input from the climate controls.
Replacement Procedure
Replacement requires access to the HVAC unit behind the dashboard. Typical steps:
- Remove glovebox or lower dash trim to reach the heater box according to workshop manual.
- Disconnect the electrical connector from the servo motor.
- Remove mounting screws/clips and extract the faulty actuator from the HVAC housing.
- Fit the new servo motor in the same position, secure fasteners and reconnect the electrical plug.
- Cycle the climate controls to verify flap travel and correct operation before reassembling trim.
Installation Recommendations
- Always Disconnect The Battery Before Starting Work To Avoid Short Circuits And Protect Electronic Components.
- Follow The Vehicle Manufacturer’s Removal Procedure; remove trim panels carefully to prevent breaking plastic clips.
- Inspect Flap Linkages And The Heater Box For Broken Teeth Or Foreign Objects That May Have Caused The Failure.
- Test The Actuator Function With The Connector Reattached Before Final Reassembly To Save Time.
- Use Proper Tools And Moderate Torque On Fasteners To Avoid Damaging The New Unit.
Why This Part Fails
- Plastic Gear Wear Or Broken Teeth Due To Age And Repeated Operation.
- Internal Potentiometer Or Position Sensor Degradation Causing Incorrect Feedback.
- Water Ingress From A Blocked Windscreen Drain Leading To Corrosion Or Seizure.
- Connector Corrosion Or Wiring Fatigue Resulting In Intermittent Or No Power.
- Obstructions Inside The Heater Box That Jam Flaps And Overload The Motor.
