Description
Heater servo motor for Citroën and Peugeot vehicles. You may receive a direct replacement. Air conditioning motor gearbox.
Description
High-quality heater servo motor compatible with a range of Citroën and Peugeot models. Designed to control flap position inside the HVAC unit, this actuator regulates airflow direction and temperature blending for reliable climate control. Ideal for professional workshops and DIY mechanics, the unit is a direct-fit replacement (reference numbers included) and restores correct vent selection and temperature response when the original actuator shows signs of failure. Common search terms: heater servo motor, HVAC actuator, blend door actuator, Valeo actuator, T1006419G, 0902111B.
Technical Information
- Manufacturer: Valeo
- Model: Citroën C2; Citroën C3; Peugeot 308
- Product Codes: T1006419G; 0902111B
- Additional Numbers: Stellantis Citroën/Peugeot references (see product codes)
Function
The servo motor (actuator) drives the internal gear mechanism of the HVAC box to move blend and distribution flaps. Proper operation ensures accurate cabin temperature control and correct air distribution (windshield, face, feet). Faulty actuators cause incorrect temperatures, stuck flaps, or clicking noises from the dashboard.
Installation Recommendations
- Disconnect the battery before starting work and follow the vehicle manufacturer’s removal and installation procedures.
- Access is typically behind the glovebox or lower dashboard trim—remove panels carefully to avoid breaking clips.
- Unplug electrical connector and remove retaining screws. Note flap position before removal to ensure correct orientation on installation.
- Inspect mating gears and HVAC housing for debris or damage; replace damaged plastic gears to avoid repeat failures.
- After fitting, cycle the climate controls through all positions to confirm smooth movement and correct temperature response before reassembling trim.
- Check connector pins for corrosion and ensure secure electrical connection. If actuator is new, verify operation with ignition on and HVAC commands before final assembly.
How Replacement Is Performed
- Park vehicle on level surface, switch ignition off and disconnect negative battery terminal.
- Remove glovebox or lower dash panel to gain access to the HVAC housing.
- Locate faulty actuator, disconnect its wiring harness and remove mounting screws.
- Fit new actuator in the same orientation, secure screws and reconnect the harness.
- Reconnect battery, start ignition and test HVAC functions for correct flap movement and lack of abnormal noises.
- Reinstall trim and verify final operation.
Common Failure Causes
- Plastic Gear Wear Or Stripping: Repeated use and load lead to gear teeth failure, causing skipping or complete loss of movement.
- Moisture And Contamination: Water ingress or debris in the HVAC box can jam gears or corrode electrical contacts.
- Motor Or Electronic Failure: Internal motor windings or small electronics can fail with age, heat, or voltage spikes.
- Connector Corrosion Or Wiring Faults: Poor connection causes intermittent operation or total loss of power to the actuator.
- Age And Fatigue: Actuators commonly degrade after years of service—symptoms include slow response, clicking noises, or stuck flaps.
Notes For Professionals And DIYers
This part is suitable for mechanics and experienced DIYers. Keep replacement codes T1006419G and 0902111B handy when searching or ordering to ensure correct match. Inspect surrounding HVAC components during replacement to prevent reoccurrence of faults.
