Description
Heating servo motor for Citroën and Peugeot vehicles. You may receive a direct replacement. Air conditioning gearmotor.
This Valeo heater servo motor (gear-reduction actuator) is designed for HVAC systems in a range of Citroën and Peugeot cars. It controls flaps and dampers inside the heating and air‑conditioning unit to route airflow and regulate cabin temperature. The unit is a direct-fit option for many Stellantis vehicles and is commonly sought under OEM codes such as T1006419G, 0109151B or 6447NL, making it easy to find by part number.
Features
– Gear‑reduction electric actuator for HVAC blend and flap control
– Compact 12 V motor design suitable for original equipment housings
– Direct-replacement form factor for straightforward swap-in installation
– Commonly supplied by Valeo for Citroën and Peugeot applications
Technical Information

Compatibility
Typical applications include (examples): Citroën C2, Citroën C3, Citroën C4 II (second generation) and Peugeot 308. Always check the part number listed on the old actuator against the numbers above to confirm compatibility.
How To Replace
Replacement is suitable for experienced DIYers and professional mechanics. Typical replacement steps:
- Disconnect the vehicle battery before any work to avoid short circuits and possible ECU errors.
- Remove the necessary lower dash trim or glovebox to access the HVAC housing — access location depends on model.
- Locate the servo motor on the heater box, unplug the electrical connector and remove the mounting screws.
- Fit the new actuator, ensuring splines/gears engage correctly with the flap mechanism. Secure with screws and reconnect the electrical plug.
- Reconnect battery and verify correct operation by cycling HVAC modes and checking flap movement and temperature control.
Mounting Recommendations
- Always disconnect the battery before starting work.
- Handle the actuator gear teeth and plastic parts carefully to avoid damage during installation.
- Ensure correct engagement of splines and that the flap moves freely before final reassembly.
- After installation, verify full range of motion and absence of binding or abnormal noise.
Why The Part Most Often Fails
Common failure modes include worn or stripped plastic gears, motor burnout due to age or overuse, and contamination or moisture ingress inside the heater box. Symptoms indicating a faulty servo motor are: intermittent or no movement of HVAC flaps, incorrect airflow direction, inability to change temperature or mode, and rattling or grinding noises from the heater box.
Notes For Mechanics And DIYers
This actuator is typically a straightforward mechanical/electrical replacement, but access and disassembly vary by model — professional experience or a service manual greatly helps. There is no fixed replacement interval: lifetime depends on vehicle usage, environment and exposure to moisture or debris.
