Description
Heater Servo Motor BEHR for PEUGEOT 3008 and 5008 First Generation. The toothed gear section can be removed and only the motor can be used.
Product Description
This BEHR heater servo motor is a direct-fit heating/ventilation actuator commonly found on first-generation Peugeot 3008 and 5008 vehicles. Designed for workshop use and confident DIY mechanics, the unit restores precise control of the HVAC flap movement and temperature distribution. The removable gear section allows you to use only the motor body if you prefer to transfer or replace the plastic gear separately, which can be useful in repairs where only the motor has failed.
Function And Benefits
The servo motor drives the HVAC blend/air distribution flaps inside the heater box, converting electrical signals from the climate control into accurate mechanical movement. Replacing a worn or faulty actuator brings back silent, smooth flap operation, correct temperature mixing and removes erratic HVAC behavior. Benefits include improved cabin comfort, straightforward installation and compatibility with common PSA part codes used in search queries.

Common Failure Modes And Lifetime
Failures are most often caused by worn or broken plastic gear teeth, motor brush wear, water ingress or seized flaps that increase load on the actuator. Electrical connector corrosion and intermittent potentiometer/position sensor faults can also produce erratic movement. Lifespan depends on vehicle usage and environment, but symptoms typically appear after several years or on higher-mileage cars.
Replacement Procedure
- Disconnect the battery before starting work to avoid short circuits and electronic damage.
- Gain access to the HVAC actuator — on these models the unit is usually mounted on the heater box behind the glovebox or beneath the centre console, depending on vehicle specification.
- Remove trim panels or the glovebox to reach the actuator. Unplug the electrical connector and remove retaining screws.
- Inspect the gear section. If you intend to reuse the original gear, carefully transfer it to the new motor; otherwise fit the actuator with the gear supplied or use the motor-only option if required.
- Refit the actuator in the correct resting position, reconnect the electrical connector and reassemble trim components.
- Reconnect the battery and test the HVAC system through full temperature and mode sweep to confirm correct operation before completing reassembly.
Installation Recommendations
- Always Verify Mechanical Freedom Of The Flaps Before Final Fitment To Avoid Immediate Re-Failure.
- Do Not Force Gears Into Position; Align Splines Carefully During Installation.
- Use Proper Fasteners And Ensure Electrical Connector Is Fully Seated And Free Of Corrosion.
- Test Full Range Of Motion And Temperature Response Before Reassembling Dash Panels.
Why The Part Most Commonly Fails
Plastic gear wear and breakage is the single most common failure cause. Repeated movement under load, thermal cycling inside the heater box and contamination (dust, debris or moisture) accelerate wear. When gears strip or the motor brushes wear out, the actuator loses ability to position the flap reliably, causing incorrect airflow or temperature control.
Notes For Professional Use
This actuator is targeted at professional mechanics and knowledgeable DIYers. It is commonly searched by the listed product codes, so include those in your order or parts lookup to speed identification and procurement.
