Description
BEHR heater servo motor for PEUGEOT 3008 and 5008 first generation. Motor only; the gear section is missing and must be fitted from your original unit.
This BEHR heater servo motor is a direct-fit replacement part designed for first-generation Peugeot 3008 and 5008 HVAC systems. The unit drives the internal air-mixing or flaps inside the heater/ventilation box and restores proper climate control functions such as temperature blend and air distribution. Supplied as motor-only — the plastic gear section is not included — so the gear from the original actuator must be transferred to this motor before installation. Ideal for mechanics and DIY enthusiasts looking for a reliable replacement motor for PSA vehicles.
Key Benefits
- Direct replacement motor for Peugeot 3008 I and 5008 I HVAC actuators.
- Restores precise flap movement for temperature and airflow control.
- Cost-effective repair when the original plastic gear is intact and can be re-used.
- Built to OE supplier standards (BEHR), suitable for workshop and DIY repairs.
How It Works
The servo motor converts electrical input from the climate control unit into rotational movement that drives the internal flaps (blend/air distribution). Correct operation ensures accurate cabin temperature and distribution. If the motor runs but the flap does not move, the most common cause is a stripped or broken plastic gear — in this case the motor itself may still be good and replacement of the motor only is a cost-effective fix.
Replacement Procedure
- Safety First: Disconnect the negative battery terminal before starting work.
- Access: On first-generation Peugeot 3008/5008 the actuator is typically located on the HVAC box behind the glove compartment or lower dash trim. Remove the glovebox or access panel to reach the actuator.
- Disconnect: Unplug the electrical connector and remove the retaining screws or clips.
- Transfer Gear: Remove the plastic gear section from the original actuator and fit it onto the replacement motor. Ensure correct seating of the gear on the motor shaft.
- Install: Refit the assembled actuator, reconnect the electrical connector and screws, then reassemble the trim or glovebox.
- Check: Reconnect the battery, power up the ignition and cycle the HVAC controls to verify flap movement and correct operation. If the system behaves erratically, inspect connectors and wiring and repeat the fitting steps.
Installation Recommendations
- Always disconnect the battery before removing or fitting the actuator to prevent electrical damage.
- Handle the small plastic gear carefully — plastic splines can be fragile and must be fully seated on the motor shaft.
- Test the actuator function before final reassembly to save disassembly time if adjustments are needed.
- If the HVAC system requires calibration after replacement, use an appropriate diagnostic tool to perform adaptation or follow the vehicle service manual procedures.
- Use basic hand tools and a clean workspace to avoid contaminating the HVAC box with debris.
Why This Part Fails
- Plastic Gear Wear or Breakage: The most common failure mode — plastic gears strip or fracture over time, especially with repeated use or when obstructed.
- Motor Wear: Brushes or bearings in the small DC motor can wear out, causing weak or intermittent movement.
- Connector Corrosion or Wiring Faults: Moisture or poor electrical contact can cause intermittent power to the motor.
- Obstruction or Excess Load: Foreign objects or a sticking flap in the HVAC box can overload the motor and accelerate gear failure.
- Typical Lifespan: Dependent on use and conditions; failures commonly appear after several years of service or high-cycle operation.
Technical Information
- Manufacturer: BEHR
- Model: Heater Servo Motor (Motor Only) — Peugeot 3008 I / 5008 I

Compatibility Notes
Fits first-generation Peugeot 3008 and 5008 models where the actuator uses the same mounting and electrical connector. Check the product codes listed above against the unit on the vehicle to confirm fitment. Remember this listing is for the motor only — transfer the plastic gear from the original actuator.
Tools Recommended
- Trim removal tools, Torx/Screwdriver set, Small socket set
- Multimeter for electrical checks
- Clean cloth and gloves for handling small plastic components
Final Advice
This motor-only solution is an economical repair when the original gear is serviceable. For workshops and experienced DIYers it restores HVAC functionality without replacing the entire actuator assembly. If multiple actuators show wear or there are electrical faults in the HVAC system, consider a broader diagnostic to identify root causes.
