Description
Overview
The Valeo heater servo motor is a direct-fit HVAC actuator designed for PSA Group vehicles. It operates the heater/vent blend and flap mechanisms inside the climate unit to regulate airflow direction and temperature distribution. Suitable for professional workshops and experienced DIY mechanics looking for a reliable replacement for a failed heater actuator.
Function And Typical Applications
This servo motor (heater actuator) controls flap position within the heater and ventilation box, enabling the HVAC system to direct air to the windscreen, face vents or footwell and to mix hot and cold air for temperature control. Commonly fitted to PSA vehicles; check the part number to confirm compatibility with specific Citroen and Peugeot models.
Symptoms And Causes Of Failure
Common symptoms of a failing heater servo motor include: inability to change airflow direction, inconsistent or incorrect cabin temperature, clicking/grinding noises from the dash area, and occasional HVAC error messages. Typical causes are worn or stripped internal gears, seized shafts from contamination or heat cycling, and electrical faults in the motor or connector.
Replacement Guide
Replacement requires basic electrical and trim-disassembly skills. Typical steps: disconnect the battery; remove the glovebox or lower dash trim to access the HVAC housing; unplug the electrical connector; remove retaining screws or clips; extract the old actuator and install the new unit, ensuring gear engagement and correct linkage alignment; reconnect the connector and test HVAC functions before reassembly. Always verify fitment by comparing part numbers and connector type.

Compatibility Notes
Typical fitment includes Citroen C2 and C3 and related PSA-platform Peugeot vehicles. Because HVAC housings and actuator linkages can vary, always confirm compatibility using the product codes above and your vehicle VIN or OEM part reference.
Why Choose This Part
Replacing a faulty heater servo motor with the correct Valeo unit restores precise HVAC control, reduces cabin noise from failing actuators and prevents prolonged discomfort due to improper airflow or temperature distribution. Ideal for garages and competent DIY installers who require an OEM-style replacement based on part number match.
