Description
Overview
Professional replacement heater actuator manufactured by BEHR, designed for PSA Group vehicles (Citroen and Peugeot). This direct-fit HVAC servo motor (EAM501) is commonly searched by part numbers 38236Ua14, 6447QN, 6447QM and 6447AW — include these codes when searching to ensure compatibility. Ideal for workshop technicians and competent DIY enthusiasts who repair climate control systems.
Function and Application
The heater actuator controls the position of HVAC flaps and blend doors to regulate airflow direction and cabin temperature. It converts electrical signals from the climate control unit into precise mechanical movement, ensuring correct distribution of hot and cold air within the passenger compartment.
Symptoms Of A Failing Unit And Common Causes
Typical symptoms include irregular airflow, incorrect temperature distribution, unusual clicking or grinding noises from the dashboard, and failure of the climate system to respond to control inputs. Failures usually result from worn internal gears, stripped plastic splines, motor burnout, moisture ingress, or electrical connector issues. Age, repeated use and exposure to humidity accelerate wear.
Replacement And Installation Notes
Replacement is straightforward for a trained technician but requires basic disassembly of the dashboard or glovebox area depending on vehicle model. General steps: disconnect the battery, remove access panels (often glovebox or lower dash), unplug the actuator electrical connector, remove mounting screws, note flap/shaft orientation for correct reassembly, install new actuator and verify full travel. After installation, cycle the HVAC controls to allow the unit to self-calibrate where applicable. Always verify part numbers and fitment before ordering and follow vehicle-specific service manual instructions for airbag and electrical safety precautions.
