Replace a worn or noisy HVAC actuator with this Valeo heater servo motor, a common original-equipment supplier part used on a range of Citroën and Peugeot models. Ideal for professional workshops and DIY mechanics, this servo motor restores precise flap and blend-door control in heating and ventilation systems, improving cabin temperature regulation and airflow distribution. Often searched by part numbers, this unit is listed under T1006419G, 0510091C and 6447NL — include these codes when checking fitment or ordering spare parts.
Technical Information
- Manufacturer: Valeo
- Model: Citroën C2, Citroën C3, Citroën C4 II, Peugeot 308
- Product Codes: T1006419G, 0510091C
- Additional Numbers: 6447NL
Function And Symptoms
This electric servo motor actuates HVAC internal flaps (blend doors and distribution flaps) to direct airflow and regulate cabin temperature. Typical symptoms of a failing unit include irregular or no airflow from vents, inability to change temperature or vent position, rattling or clicking noises from the dashboard area, and inconsistent climate control behavior.
How Replacement Is Performed
Replacement Procedure (Typical):
- Disconnect the negative battery terminal before any work to avoid short circuits and retain electronic safety.
- Gain access to the HVAC unit — this commonly requires removing the glovebox or lower dash trims on the affected model.
- Locate the faulty actuator on the HVAC housing, unplug the electrical connector, and remove the mounting screws.
- Fit the new servo motor, secure with the original fasteners, reconnect the electrical connector and reassemble the dash components.
- Verify correct operation by cycling HVAC modes and observing flap movement and vent function.
Exact disassembly steps vary by model; follow vehicle manufacturer procedures and torque settings where specified.
Installation Recommendations
- Always Disconnect The Battery Before Starting Work.
- Inspect Linkages, Splines And The Surrounding HVAC Housing For Wear Or Broken Plastic Teeth — Replace Any Damaged Parts To Prevent Premature Failure.
- When Reinstalling, Ensure The Flap Positions Are Correct To Avoid Binding Or Incorrect Calibration.
- Test HVAC Functions Immediately After Installation To Confirm Smooth Movement And Absence Of Unusual Noises.
- Use A Clean Work Area To Avoid Introducing Debris Into The HVAC System.
Why The Part Most Commonly Fails
- Plastic Gear Wear Or Broken Teeth From Age And Repeated Movement.
- Motor Brush Wear Or Internal Motor Degradation After High Mileage.
- Ingress Of Moisture Or Dust Leading To Corrosion And Mechanical Jamming.
- Heat And Thermal Cycling From The HVAC Environment Causing Material Fatigue.
For mechanics and experienced DIYers, replacing the actuator is a cost-effective repair that restores reliable climate control. When ordering, include the part numbers T1006419G, 0510091C or 6447NL to improve the chance of immediate fitment and fast delivery.
