Product Overview
The BEHR Heater Servo Motor is a direct-replacement HVAC actuator designed for Citroën and Peugeot vehicles. Supplied under part codes EAM501, A7583Ua13 and 6447QN, this servo controls interior air distribution and the temperature blend doors to ensure accurate cabin climate control. The unit is suitable for professional mechanics and experienced DIYers who perform HVAC repairs.
Features And Function
This servo motor actuates heater and blend doors inside the HVAC housing, enabling precise mixing of warm and cold air and correct airflow direction. Its compact design aims for OEM-style fitment and integrates with the factory wiring harness for straightforward installation where applicable.
Common Symptoms And Causes Of Failure
Typical symptoms of a failing heater servo include incorrect cabin temperature, uncontrolled or incorrect airflow direction, intermittent movement or complete loss of door function, and audible clicking or grinding noises from behind the dashboard. Common causes are plastic gear wear, contamination or debris in the heater box, connector corrosion, and long-term thermal stress or aging components.
Replacement And Installation
Access is usually through the glove compartment or lower dashboard area to reach the heater box. General replacement steps: disconnect the battery, remove trim or glovebox panels to gain access, unplug the electrical connector, remove retaining screws, swap the actuator, secure the new unit and reconnect. Some vehicles require an initialization or end-stop calibration sequence after installation; consult the factory workshop manual for the exact procedure. Always confirm fitment by checking the part number against the vehicle VIN before ordering.
