Description
Heater Servo Motor For CITROEN And PEUGEOT Vehicles. You May Receive A Direct Replacement. HVAC Gearmotor.
High-quality replacement heater servo motor (HVAC gearmotor) compatible with a range of Citroën and Peugeot models. This compact electric actuator controls airflow doors and temperature blend flaps inside the climate control unit, restoring precise HVAC function and eliminating irregular airflow, unwanted noises or inability to change cabin temperature. Ideal for professional workshops and experienced DIY mechanics who search by part number (Valeo T1006419G / 1411111B / 6447NL) to find a direct-fit solution.
Key Benefits
- Direct-Fit Replacement: Built to match original mounting points and electrical connector for straightforward swap.
- Restores HVAC Control: Eliminates clicking or failure to move blend/vent flaps, improving cabin comfort and climate accuracy.
- Durable Gearmotor: Metal and engineered-plastic components designed for long service life under normal operating conditions.
- Searchable By Part Number: Frequently located by reference numbers T1006419G, 1411111B or 6447NL — useful for fast identification.
Technical Information
- Manufacturer: Valeo
- Model: Citroën C2; Citroën C3; Citroën C4 II; Peugeot 308 (models with compatible HVAC units)
- Product Codes: T1006419G; 1411111B

How The Part Works
The servo motor drives a small reduction gearbox and an output shaft or spline that moves HVAC flaps inside the climate box. Depending on the function it serves, the actuator positions blend doors (temperature mixing), mode doors (vent distribution) or recirculation/air intake flaps to achieve the commanded climate settings from the control unit.
Typical Replacement Procedure
Procedure Overview (General Guidance):
- Disconnect Battery: Always disconnect the negative terminal before starting to prevent electrical damage.
- Access HVAC Unit: Remove glovebox or lower dashboard trim panels to reach the HVAC housing—location varies by model.
- Locate Actuator: Identify the faulty servo mounted to the heater/evaporator housing. Note the flap linkage orientation before removal.
- Disconnect Electrical Connector: Unplug the wiring harness and remove mounting screws securing the actuator.
- Replace Unit: Fit the new servo ensuring correct spline engagement and secure screws without over-torquing.
- Reconnect And Test: Reconnect battery, power up ignition and run climate controls through full travel to confirm correct operation and self-calibration.
Note: On some vehicles the actuator performs a self-calibration routine at first power-up; if movement is restricted, avoid forcing the mechanism and recheck fitment.
Installation Recommendations
- Disconnect Battery Before Work: Prevents short circuits and protects HVAC electronics.
- Preserve Seals And Insulation: Avoid damaging foam seals around the HVAC housing to prevent air leaks and noise.
- Check Linkages And Flaps: Inspect adjacent plastic gears, splines and flap shafts for wear before reassembly.
- Use Correct Fasteners: Tighten mounting screws to original specifications; avoid over-tightening which can deform the housing or strip threads.
- Perform Functional Check: Cycle temperature and vent modes to ensure full range movement and absence of binding or noise.
Why This Part Commonly Fails
Common Causes Of Failure:
- Worn Or Stripped Plastic Gears: Repeated movement and age can wear teeth, causing slipping or loss of position.
- Brush Or Motor Wear: Internal motor brushes and commutator wear out over time, leading to intermittent operation or complete failure.
- Moisture And Contamination: Water ingress or debris in the HVAC box can seize gears or corrode contacts.
- Mechanical Impact Or Misalignment: Poor previous repairs or forced movement can damage splines and levers.
- Electrical Issues: Connector corrosion or wiring faults can prevent power delivery to the motor.
Typical Service Life: Depends on usage and environmental conditions; failure is common after many years or high mileage when plastic components and small motors reach the end of their fatigue life.
Compatibility And Identification
This actuator is commonly used on selected Citroën and Peugeot models. Buyers searching by part number (T1006419G, 1411111B, 6447NL) increase the chance of finding the correct replacement quickly. Always verify the part shape, connector and mounting pattern against the unit being replaced before installation.
