Description
Heater servo motor for Citroën and Peugeot vehicles. Air-conditioning actuator motor.
High-quality Valeo heater servo motor designed for climate control systems on selected Citroën and Peugeot models. This actuator operates flap and blend mechanisms inside the HVAC box to control airflow direction and temperature mix. It is a direct-replacement electrical servo unit commonly referenced by part numbers T1006419G, 0510091C or 6447NL, making it easy to find in catalogs and search engines.
Why This Part Matters
Faulty heater servo motors cause incorrect airflow distribution, inability to change temperature, or clicking/grinding noises from the dashboard. For workshops and experienced DIYers this Valeo servo is a straightforward upgrade to restore precise climate control response. Clear reference to the product codes in the description improves findability for mechanics searching by part number.
Compatibility
Typical fitment (use the listed codes to confirm for your vehicle): Citroën C2, Citroën C3, Citroën C4 II, Peugeot 308. Part numbers: T1006419G | 0510091C | 6447NL.
Technical Information
- Manufacturer: Valeo
- Model: Citroën / Peugeot HVAC Servo Motor
- Product Codes: T1006419G, 0510091C, 6447NL
- Additional Numbers: 0510091C
Typical Symptoms And Fault Causes
- Symptoms: Inability to change vent position or cabin temperature, intermittent operation, repetitive clicking or grinding noises from the dashboard area.
- Common Causes: Worn plastic gears inside the actuator, motor wear or electrical connector faults, contamination or water ingress into the HVAC box, and long-term mechanical fatigue of internal components.
- Life Expectancy: Variable depending on use and environment; failures are more common after several years of operation or after exposure to moisture and debris.
Replacement Guide (General)
Replacement procedures vary by model and HVAC layout. General steps for experienced technicians or competent DIYers:
- Disconnect Battery: Always disconnect the negative battery terminal before starting to avoid electrical damage and to protect vehicle electronics.
- Access HVAC Unit: Remove necessary trim (glovebox, lower dash panels or center console) to reach the HVAC plenum where the actuator is mounted.
- Disconnect Connector: Unplug the electrical connector from the servo motor.
- Remove Fasteners: Unscrew the retaining screws or release the clips securing the actuator and extract it from the HVAC housing.
- Fit New Unit: Install the new servo in the correct orientation, secure fasteners, and reconnect the electrical plug.
- Function Check: Reconnect battery, run the climate system through all modes and temperatures to verify correct flap movement, absence of abnormal noises and proper HVAC function.
Installation Recommendations
- Follow Manufacturer Procedures: Refer to the vehicle repair manual for model-specific removal and reassembly instructions and torque values.
- Protect Electronics: Disconnect the battery and avoid shorting connectors; ensure connectors and seals are clean and dry before reconnection.
- Calibration: Some HVAC systems may require a simple calibration cycle (cycling through modes) or an initialization procedure after replacement—follow the vehicle-specific instructions.
- Use Correct Part Codes: Confirm that the part numbers match those listed for your vehicle to ensure correct fit and gear orientation.
Most Common Repair Reasons
Servo motors in climate systems are subject to mechanical stress and environmental contamination. Plastic gear teeth can shear or deform, motors can wear out, and electrical contacts can corrode. Replacing the actuator restores precise airflow control and eliminates noise or intermittent operation that impairs cabin comfort.
For Whom
This product is aimed at professional auto technicians and experienced DIYers who perform climate system repairs on Citroën and Peugeot vehicles. Use the product codes when searching or ordering to speed up matching and reduce downtime.
