Description
Overview
The BEHR heater servo motor (blend door/air flap actuator) EAM501 is a direct-fit HVAC actuator for a range of PSA Group vehicles. Designed to control heater and ventilation flaps inside the heater box, it ensures accurate cabin temperature distribution and reliable airflow direction control for both professional workshops and DIY mechanics.
Benefits
- Direct replacement with OEM-equivalent fitment for Citroën and Peugeot models.
- Restores proper flap movement and temperature control, removing erratic climate behaviour.
- Robust solution for garages and independent repairers seeking a fast HVAC repair.
Symptoms Of Failure And Causes
Common symptoms include no change in airflow direction, inability to adjust cabin temperature, intermittent or continuous clicking noises from behind the dashboard, or stuck vents. Typical causes are worn or stripped plastic gears, motor winding failure, moisture ingress, or connector/wiring faults. Lifespan varies with use and environment; failures often appear after several years of operation.
Installation Notes
Replacement is straightforward for a trained mechanic: disconnect the vehicle battery, remove the necessary lower dash panels to access the heater box, unplug the electrical connector and remove the actuator mounting screws or clips. Fit the new unit, secure screws, reconnect the plug and reassemble panels. After installation, cycle the ignition and HVAC controls to allow the actuator to find end positions; many PSA vehicles perform an automatic calibration routine.
