Description
Overview
High-quality Valeo heater servo motor designed for Citroën and Peugeot HVAC systems. This servo actuator, listed under part numbers T1006419G and 0902111B, is a direct-fit replacement commonly sourced from a Peugeot 308 (2011). It restores precise control of heater and blend flaps, bringing back reliable cabin temperature regulation and airflow distribution. Ideal for professional mechanics and competent DIY technicians working on PSA vehicles.
Key Benefits
- Direct-fit replacement for compatible Citroën and Peugeot HVAC units using the listed part numbers.
- Restores accurate flap positioning for even cabin heating and efficient climate control.
- Plug-and-play electrical connector compatible with original harnesses on applicable PSA models.
- Suitable for workshops and DIY repairs where part-number matching is used to confirm fitment.
Fitment & Replacement
Fitment: Originates from Peugeot 308 (2011) and fits PSA vehicles that use the same heater box actuator with part codes T1006419G / 0902111B. Always verify compatibility by comparing part numbers before ordering.
Replacement Overview: Typical replacement requires interior trim removal to access the HVAC housing (often via glovebox or lower dash panel). Steps: disconnect battery, remove necessary trim, unplug the actuator electrical connector, remove retaining screws, replace the actuator and reassemble. After installation, cycle the climate control to verify full travel of heater/blend flaps and correct operation.
Common Failure Modes
Servo actuators in PSA HVAC systems commonly fail due to worn or stripped plastic gear teeth, seized small DC motors, water or debris ingress, or electrical connector corrosion. Symptoms include incorrect temperature, stuck or drifting flap positions, unusual noises from the dash, or complete loss of flap movement. Lifespan varies widely with usage and vehicle environment; failures are often gradual and first noticeable as intermittent operation or noise.
Installation Tips
- Handle the actuator gears carefully; avoid forcing the mechanism during installation.
- Check connector pins for corrosion and ensure a solid electrical connection.
- After fitting, perform a full HVAC calibration cycle if the vehicle system requires it (consult vehicle service manual).
