Description
BEHR heater servo motor for Peugeot 3008 and 5008 first generation. The toothed gear section can be removed and the motor can be used alone.
This BEHR heater servo motor is a direct replacement part designed for the HVAC system in first‑generation Peugeot 3008 and 5008 vehicles. It controls flap movement inside the heater/ventilation box to regulate airflow and temperature blend. The compact electric motor is ideal for professional workshops and experienced DIY mechanics seeking a reliable replacement motor — especially when the plastic gear section is damaged but the motor itself remains serviceable. Commonly searched by product codes Z5509001, 2706149C and 647997.
Technical Information
Manufacturer: BEHR
Model: Peugeot 3008 I, Peugeot 5008 I (First Generation)
Product Codes: Z5509001, 2706149C, 647997
Other Numbers: No additional OEM references available
Function And Benefits
The servo motor actuates blend or distribution flaps inside the heater box, ensuring precise control of cabin temperature and airflow direction. Replacing a faulty servo motor restores accurate flap movement, eliminates unwanted noises or stuck positions, and improves climate control performance. The removable gear segment allows reuse of the motor alone if the plastic gear has broken, which can reduce repair costs.
Compatibility And Fitment
Intended For: Peugeot 3008 I and Peugeot 5008 I (first generation). Verify the physical connector, mounting points and shaft/gear interface against the old unit before installation. Searching by product codes Z5509001, 2706149C or 647997 often returns matching listings.
How To Replace
- Disconnect the negative battery terminal before beginning work to avoid short circuits and accidental motor actuation.
- Gain access to the heater box — this usually requires removal of lower dash panels or glovebox depending on vehicle layout.
- Locate and unplug the electrical connector from the servo motor.
- Remove the retaining screws or clips and detach the actuator from the flap shaft.
- If reusing only the motor, carefully separate the removable toothed gear segment and fit the motor to the shaft as required.
- Install the new motor, verify full range of motion by briefly reconnecting the battery and cycling the HVAC controls, then reassemble panels.
Installation Recommendations
- Test the new unit for correct movement and absence of grinding or binding before final reassembly.
- Ensure the flap linkage is aligned and free of debris; damaged plastic gears should be replaced or drive adapted correctly.
- Use proper hand tools and avoid over‑tightening retaining screws to prevent housing damage.
- When reusing the motor only, confirm the mating gear profile and secure fit to prevent slippage.
- Check connector pins for corrosion and ensure a firm electrical connection to avoid intermittent operation.
Why This Part Most Often Fails
Failures are typically caused by worn motor brushes, seized bearings, or stripping of the small plastic gears that drive the HVAC flaps. Heat cycles, humidity, and aging of plastic components accelerate wear. Symptoms include grinding or clicking noises, partial or no flap movement, incorrect temperature distribution, and random flap positions.
Why Choose This Replacement
Choosing a quality BEHR replacement motor restores precise flap control and can be a cost‑effective repair, especially when the motor remains serviceable and only the plastic gear needs replacement. The removable gear option allows flexible repair strategies for garages and skilled DIYers.
