This Valeo heater servo motor is a direct-fit HVAC actuator designed for Citroën C4 II and Peugeot 308 T7 models. It controls the movement of heater/ventilation flaps to regulate airflow direction and blend temperature inside the passenger compartment. The part is commonly searched by product codes such as T1009914P and 6479E7, making it easy for professional technicians and DIY enthusiasts to find the correct replacement.

Designed for workshops and competent DIY mechanics, this servo motor restores precise flap control, eliminates erratic ventilation behaviour and reduces unwanted noises from the dashboard area. Typical symptoms that indicate a faulty actuator include inconsistent air distribution, inability to change temperature properly, clicking or grinding noises behind the dash, and stuck vent doors. Replacing the faulty actuator returns full HVAC functionality and improves cabin comfort.

Technical Information

• Manufacturer: Valeo
• Model: Citroën C4 II; Peugeot 308 T7
• Product Codes: T1009914P; A 6479E7
• Other Numbers: 64790000000

Function

The unit is an electric servo (HVAC actuator) that drives heater and ventilation flaps (air distribution and blend doors). It converts electrical control signals from the climate control module into mechanical movement of internal ducts, enabling proper temperature mixing and airflow direction.

How To Replace

• Safety First: Always disconnect the battery before starting work to avoid short circuits and potential damage to electronic components.
• Access: Depending on the model, access is typically gained by removing the glovebox or a small dashboard panel on the passenger side to reach the HVAC housing.
• Disconnect: Unplug the electrical connector and remove the retaining screws or clips that hold the actuator in place.
• Remove & Install: Remove the old actuator, fit the new unit in the same orientation, secure fasteners and reconnect the electrical connector.
• Test: Reconnect the battery, cycle the ignition and operate the climate controls to verify smooth flap movement and correct airflow. In most cases the actuator is plug-and-play and requires no additional programming.

Installation Recommendations

• Follow vehicle manufacturer access and removal procedures to avoid damaging dash trim or HVAC components.
• Handle the servo and its plastic gears carefully; do not force linkages when fitting to prevent gear stripping.
• Check and clear any debris or foreign objects inside the HVAC housing that might obstruct flap movement.
• If unusual noises persist after replacement, inspect linkages and duct mounts for binding or broken clips.

Why The Part Most Commonly Fails

Actuators commonly fail due to worn or stripped plastic gears, internal potentiometer wear, motor burnout from prolonged use or overload, and ingress of moisture or dust leading to corrosion. Repeated full-range cycling, high mileage, and brittle plastic after long-term heat exposure accelerate wear. Mechanical stress from obstructed flaps or broken mounting points can also cause premature failure.

Buy this Valeo heater servo motor if you need a reliable replacement for faulty HVAC flap control on Citroën C4 II or Peugeot 308 T7. The product codes listed above help ensure quick identification and fitment for repair jobs in the workshop or for competent DIY maintenance.

Original VALEO heating servomotor for Citroën and Peugeot. This electric drive HVAC flap ensures accurate reconstruction of the mixing and distribution flaps in the heating/air conditioning unit. If you hear repeated clicking from the dashboard in the car, the temperature cannot be changed, the air flow remains only for one setting or only works on one side, the flap servomotor is to blame.

The part is suitable as a replacement for the original component of dog vehicles, where it is usually marked with code 6479E7 (OE) and production designation Valeo N101980g/E. It is often found, for example, with the Citroën C3 Picasso, Citroën C4 II and Peugeot 308. Thanks to the same geometry and electric interface, it fits into its original location without modifications and restores the correct air conditioning and heating function.

Installation is usually accessible from the passenger compartment after dismantling the side cover or clipboard (different according to the model). After disconnecting the battery, the electric connector is unlocked, the fastening screws of the servos are unscrewed and the part is simply exchanged for the original. After re -connecting the battery, leave the ignition on for several tens of seconds – the air conditioning control unit usually initiates the end positions of the flaps.

For accurate pairing according to the part, we recommend comparing the numbers from your original servos (label on the body) with the codes below. Properly selected servomotor saves time when repairing and stabilizes the operation of heating and air conditioning without unwanted sounds and irregular flow.

• Product codes: Valeo N101980g/E | PSA 6479E7
• additional numbers: 94W1C (94W1C)

The key advantage of the original VALEO part is to the precise operation of the gear mechanism and a reliable position sensor that is critical for the smooth control of the flaps. A properly functioning servomotor significantly improves the comfort of the crew – the temperature and flow direction are set quickly and flawlessly.

Compatibility / Fitment

Compatible with Citroën C4 II and Peugeot 308 T7 climate control systems where the OEM part numbers match T1002120V or 6479E7. Always verify the part number shown on the original actuator before ordering to ensure correct fitment.

Function And Symptoms

This servo motor (blend door actuator) moves internal flaps that direct airflow and mix hot and cold air to reach the selected cabin temperature. Common symptoms of a failing unit include:

• Inability to change temperature or airflow direction.
• Unusual clicking or grinding noises from the dashboard when adjusting climate settings.
• Intermittent or complete loss of movement of ventilation flaps.

Replacement Procedure (Overview)

Replacement typically requires removing trim panels or the glove box to access the HVAC case on the passenger side. General steps:

• Disconnect the vehicle battery to avoid electrical shorts.
• Remove glove box or lower dash panels to expose the actuator housing.
• Unplug the electrical connector and remove fasteners securing the actuator.
• Replace with the new unit, secure fasteners and reconnect the connector.
• Reassemble trim panels and reconnect the battery.

On some vehicles the actuator will self-calibrate after power-up; on others a simple cycle of the climate controls (or ignition cycles) is sufficient. If symptoms persist, check for obstructions or damaged flap linkages inside the HVAC box.

Installation Recommendations

• Disconnect the battery before starting work and follow manufacturer repair procedures to prevent damage and ensure safety.
• Inspect the HVAC housing and flap mechanisms for broken plastic tabs or debris before installing the new actuator.
• Fit the actuator in the correct orientation and avoid forcing gear engagement; stripped gears are a common secondary failure.
• Use proper trim tools to avoid damaging panels and fasteners during removal.

Why This Part Fails

Heater servo motors commonly fail due to wear of the small plastic gears, long-term exposure to heat and humidity, contamination from debris or liquids in the HVAC casing, or mechanical overload when flaps or linkages are broken. Electrical connector corrosion and intermittent wiring faults can also cause loss of function or erratic movement.
