Description
Product Overview
The Bosch heater servo motor 0132801169 (6447HL) is a direct-fit HVAC actuator used in PSA Group vehicles. It operates the blend and distribution doors inside the heating and ventilation system to regulate cabin temperature and airflow. Designed for professional mechanics and experienced DIY technicians seeking a reliable replacement part.
Applications
Function And Common Failures
This servo motor moves the blend door and air distribution flaps to mix hot and cold air and direct airflow to the chosen vents. Common failure modes include worn or stripped plastic gears, seized motor bearings, electrical connector corrosion, or failure of internal position feedback. Typical symptoms are no temperature change, stuck vent selection, intermittent operation or unusual clicking/noise from the dashboard area.
Replacement & Installation
- Disconnect the vehicle battery before starting to avoid short circuits.
- Access the actuator by removing the glovebox, lower dash trim or center console depending on vehicle model.
- Unplug the electrical connector and remove the mounting screws securing the servo motor.
- Transfer any linkage or alignment marks, fit the new actuator, secure fasteners and reconnect the wiring.
- Reconnect the battery and verify full range of motion through the HVAC controls; perform any required calibration or system resets per vehicle service manual.
Service Life And Tips
Service life varies with use and environmental conditions; failure often results from age-related wear or moisture-related connector issues. When replacing, inspect associated HVAC linkages and connectors for damage. Use gentle handling to avoid damaging plastic gears during installation.
