Description
Overview
High-quality Heater Servo Motor (HVAC Actuator) manufactured by BEHR, designed as a direct-fit replacement for PSA group vehicles. This actuator controls heater/vent flap movement to ensure accurate cabin temperature regulation. Commonly referenced by part numbers 38236Ua13 and 6447QN, it is intended for professional garages and competent DIY mechanics who service Citroën and Peugeot models.
Key Benefits
- Precise control of heater and blend doors for reliable temperature regulation.
- Direct-fit design reduces installation time and alignment effort.
- Suitable for workshop replacement or owner repairs; often searched by OE codes for fast identification.
Compatibility & Typical Applications
Primarily used on PSA vehicles, notably Citroën and Peugeot models in the C2 and C3 range as indicated by the provided fitment references. Always verify fitment using the vehicle VIN or by matching the part numbers 38236Ua13 / 6447QN before purchase.
Symptoms Of Failure
Failing heater servos typically present as: unchanging cabin temperature despite control input, inconsistent airflow direction, abnormal clicking or grinding noises from the dash, or an error code related to HVAC actuation. These symptoms indicate worn internal gears, motor burnout, or connector/electrical faults.
Replacement Guidance
Typical replacement steps (general guide): disconnect the battery; remove lower dash panels or glove box to access the HVAC housing; locate and unplug the actuator electrical connector; remove mounting screws and extract the faulty actuator; install the new BEHR unit, secure fasteners, reconnect the connector and restore power. After installation, cycle ignition and HVAC controls to confirm full range of motion and correct operation. If required, perform actuator calibration or follow vehicle-specific initialization procedures.
Common Causes Of Failure
- Wear of plastic internal gears over time due to frequent operation.
- Ingress of moisture or debris causing friction and jamming.
- Electrical issues such as connector corrosion or motor winding faults.
