Description
BEHR heater servo motor for Peugeot 3008 and 5008 first generation. The gear section can be removed and the motor used separately.
This BEHR heater servo motor is a direct-fit electric actuator designed to control HVAC flaps in first‑generation Peugeot 3008 and 5008 vehicles. Suitable for professional workshops and experienced DIYers, the unit is often sought by its product codes and original equipment references. The compact motor provides reliable flap movement and can be installed as a complete actuator or, in applications where the gearbox is damaged, the removable gear section allows reuse of the motor only.
Key Benefits
- Direct fit for specified models—simplifies replacement and reduces downtime.
- Removable gear section—option to replace only the motor if the plastic gears are worn.
- Quality BEHR component—designed for HVAC control in Stellantis vehicles.
How It Works
The servo motor drives the HVAC blend/air‑distribution flaps inside the heater unit. It converts electrical pulses from the climate control module into rotary motion, moving the internal gears and linkages that open, close, or blend airflow. Proper operation ensures accurate cabin temperature and air distribution.
Installation Instructions
- Disconnect the vehicle battery before starting work to avoid short circuits and protect vehicle electronics.
- Access the actuator—typically located behind the dashboard or glovebox on the heater box. Remove trim or glovebox as needed to reach the unit.
- Unplug the electrical connector and remove mounting screws. Note actuator orientation and gear engagement for correct reassembly.
- If reusing only the motor, carefully remove the plastic gear section and mount the motor in the intended location, ensuring correct alignment and secure fixing.
- Reconnect the connector, reconnect the battery, and cycle the climate control through full range to verify flap movement and correct operation before reassembling trim.
- Some systems may require calibration or a flap adaptation routine—verify actuator movement and HVAC behaviour after fitment.

Recommended For
Professional technicians and competent DIYers replacing faulty HVAC actuators in first‑generation Peugeot 3008 and 5008. Especially useful when the motor is still functional but plastic gears are damaged — the removable gear section allows economical repair options.
Why This Part Fails Most Often
- Worn Or Broken Plastic Gears: Repeated movement and aging commonly strip or fracture the small plastic teeth, causing intermittent or stuck flaps.
- Moisture And Dirt Ingress: Condensation or debris inside the heater box can accelerate wear or seize the mechanism.
- Electrical Motor Wear: Brushes or bearings in the small DC motor can deteriorate over time, reducing torque or causing failure.
- Excessive Load From Damaged Linkages: Misaligned or damaged flap linkages can overload the motor and lead to premature failure.
Recommendation For Installation
- Always disconnect the battery before removal and follow manufacturer procedures to avoid damage to electronics.
- Inspect surrounding linkages and blend doors—replace or clean if worn to prevent repeated failures.
- When only the gears are damaged and the motor is in good condition, using the removable gear section can be a cost‑effective repair, but ensure secure fit and proper mesh.
- After fitting, verify full travel of flaps and correct operation of climate functions before reassembling interior trim.
