Description
Direct-fit auxiliary air (heater/blower) fan assembly for the right (passenger) side of Citroën C8 and Peugeot 807 models. Supplied complete with the blower resistor, this unit replaces worn or failed passenger-side HVAC fans and restores proper airflow for heating, ventilation and defogging. Frequently searched under part numbers 1485724080 and 6441AV — ideal for professional workshops and experienced DIYers who need a reliable, OEM-compatible replacement.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën C8, Peugeot 807

- Other Numbers: N/A
Function
The auxiliary air fan supplies conditioned air within the vehicle HVAC system on the passenger side. It supports cabin heating, accelerates windshield defogging, and balances airflow distribution when the primary blower cannot meet demand. The included resistor controls fan speed stages for smooth operation across settings.
How To Replace
Typical replacement is straightforward for a trained technician or an experienced DIYer with basic tools. General steps:
- Disconnect the battery before starting to avoid electrical shorting.
- Remove lower glovebox trim or access panel on the passenger side to reach the blower housing.
- Unplug the electrical connector and detach the resistor if separate.
- Unscrew mounting fasteners and extract the old fan assembly.
- Fit the new fan, secure mounting bolts, reconnect the resistor and electrical connector, then reassemble trim panels.
Follow manufacturer torque values and assembly order where specified. If unsure about access or wiring, consult workshop literature or a qualified technician.
Installation Recommendations
- Always disconnect the battery before any electrical work.
- Check the connector and wiring for corrosion or heat damage and replace or repair as needed.
- Install the supplied resistor and confirm that all fan speed stages operate correctly after installation.
- Test the HVAC system for proper airflow and absence of abnormal noises before returning the vehicle to service.
Most Common Failure Causes
- Worn motor brushes or bearings leading to noisy operation or complete seizure.
- Resistor failure causing loss of some or all fan speed settings.
- Water ingress or debris contamination reducing performance or shorting the motor.
- Connector corrosion or damaged wiring causing intermittent operation.
Compatibility & Notes
Fits passenger side on Citroën C8 and Peugeot 807 models that use the corresponding blower assembly design. Confirm the part numbers 1485724080 or 6441AV when searching or ordering to ensure correct fitment. This unit is intended as a direct replacement for failed passenger-side HVAC fans and includes the blower resistor required for proper speed control.
