Description
Left Auxiliary Air Fan For Vehicles Citroën C8 And Peugeot 807
Driver Side
Overview
This Left Auxiliary Air Fan is a direct-fit electrical component designed for the Citroën C8 and Peugeot 807 HVAC systems. Positioned on the driver side, the fan supports cabin air circulation and complements the main blower to ensure efficient heating, ventilation and air conditioning performance, especially in dual-zone and complex ducting layouts common to these MPV models.
Key Benefits
- Restores proper airflow to the driver side vents and improves HVAC responsiveness.
- Reduces uneven cabin temperatures and eliminates weak or intermittent airflow at low or high fan speeds.
- Direct replacement for original equipment numbers to simplify parts lookup and ordering.

Function
The Auxiliary Air Fan supports the vehicle HVAC system by driving air through secondary ducts and outlets. It helps maintain consistent cabin temperatures, assists demisting/defogging on the driver side, and takes load off the main blower under specific operating modes.
Common Failure Modes
- Worn Bearings Causing Noise Or Reduced Speed — Over Time Bearings Wear Out, Producing Grinding Or Rattling.
- Contamination — Dust, Debris Or Leaves In The Housing Can Block The Fan Wheel And Reduce Airflow.
- Moisture And Corrosion — Water Ingress Can Damage The Motor Or Electrical Connectors.
- Electrical Faults — Intermittent Operation May Be Caused By Connector Corrosion, Broken Wires Or a Failed Motor.
Expected Service Life
Service life Depends On Use And Environment. Under Normal Conditions The Fan Typically Lasts Several Years; Failures Are Often Observed After Long Service (Multiple Years Or High Mileage) When Bearings Wear Or Contaminants Accumulate.
Replacement Procedure (Overview For Mechanics And DIY)
Basic Steps To Replace The Fan:
- Prepare The Vehicle: Park On Level Ground, Switch Off Ignition And Disconnect The Negative Battery Terminal To Prevent Short Circuits While Working On Electrical Components.
- Access The Unit: Remove Relevant Interior Trim Or Glovebox Panels To Reach The HVAC Housing On The Driver Side. Some Models Require Removing The Under-Dash Panel Or Access Cover.
- Disconnect Electrical Connector: Unplug The Fan Harness Carefully And Inspect For Corrosion Or Damage.
- Unbolt And Remove Old Fan: Remove Fasteners Retaining The Fan Assembly And Extract The Unit From The Housing.
- Install Replacement Fan: Fit The New Fan In Correct Orientation, Secure Fasteners To Specified Torque, Reconnect The Electrical Connector And Reassemble Trim.
- Test Operation: Reconnect Battery, Start The Vehicle, Cycle All Fan Speeds And Modes To Verify Smooth Operation, No Unusual Noise And Proper Airflow To Driver Side Vents.
Installation Recommendations
- Always Disconnect The Battery Before Working On Electrical Components To Avoid Short Circuits.
- Inspect Wiring And Connectors During Replacement; Repair Any Corroded Or Damaged Terminals To Prevent Future Failures.
- Clean The Fan Housing And Ducts Of Debris Before Installing The New Unit To Maximize Airflow And Lifespan.
- Use Correct Fasteners And Avoid Over-Tightening To Prevent Housing Distortion Or Noise.
- After Installation, Confirm Operation Across All Fan Speeds And Check For Unusual Vibrations Or Noise That May Indicate Obstruction Or Misalignment.
