Product Overview
This right‑rear heater blower fan is a direct replacement part designed for first generation Citroën C4 Picasso and Grand C4 Picasso models. The unit moves warmed or cooled air through the vehicle HVAC system to the rear cabin and ensures consistent airflow for passenger comfort. It is a commonly replaced component when passengers report reduced airflow, unusual noise from the rear of the cabin, or intermittent heating and ventilation performance.
Technical Information
- Manufacturer: Stellantis / Citroën / Peugeot
- Model: Citroën C4 Picasso (First Generation), Citroën Grand C4 Picasso (First Generation)
- Product Codes: 9650872480, 6441X5
- Other Numbers: No Additional Numbers Provided
Compatibility
Intended For: Citroën C4 Picasso I (first generation) and Citroën Grand C4 Picasso I (first generation). Always check the part numbers when searching; this blower is frequently located in parts listings under the OEM codes 9650872480 or 6441X5.
Installation Guide
- Tools Required: Torx/Screwdriver Set, Trim Removal Tools, Socket Set, Multimeter (for basic checks).
- Access: The blower is installed at the right rear area of the HVAC housing. Depending on interior trim, it may be necessary to remove rear trim panels or access panels in the luggage compartment or behind interior cladding to reach the unit.
- Procedure Summary: 1) Disconnect the negative battery terminal. 2) Remove the trim/cover panels to reach the blower assembly. 3) Disconnect the electrical connector and any fasteners securing the fan. 4) Remove the old blower, compare mounting points and connector, and install the replacement. 5) Reconnect the electrical connector, refit panels, and reconnect the battery. 6) Test all blower speeds and HVAC functions before finalizing reassembly.
- Note: The Fan Speed Regulator Is Often A Separate Component And Can Be Purchased Separately; Verify Regulator Condition When Replacing The Blower.
Recommended Installation
- Always Disconnect The Battery Before Starting Work To Avoid Short Circuits And Protect Vehicle Electronics.
- Inspect The Connector Pins And Wiring For Corrosion Or Damage; Repair Any Faulty Wiring Before Installing The New Blower.
- Use Correct Fasteners And Torque Settings Where Specified By The Manufacturer To Prevent Rattles Or Air Leaks.
- After Installation, Cycle Through All Fan Speeds And Modes To Confirm Proper Operation And Listen For Unusual Noises Indicative Of Misalignment Or Foreign Objects.
- Keep The Work Area Clean And Remove Any Debris From The HVAC Housing To Prevent Premature Wear Of The New Fan.
Why This Part Most Often Fails
- Mechanical Wear: Bearings Inside The Blower Motor Wear Over Time, Causing Noise And Reduced Rotation Efficiency.
- Debris Infiltration: Leaves, Dust And Small Objects Entering The HVAC Housing Can Jam The Fan Or Damage The Impeller.
- Moisture And Corrosion: Water Ingress Or Corroded Connectors Can Cause Intermittent Operation Or Electrical Failure.
- Overload And Electrical Issues: Faulty Resistors Or Voltage Surges May Lead To Motor Burnout; The Speed Regulator Failure Can Also Mimic A Blower Fault.
Additional Notes
This blower is often searched by its OEM product codes (9650872480, 6441X5). If the vehicle exhibits weak rear airflow, noise from the rear cabin area, or complete loss of blower function on multiple speeds, replacing the right‑rear heater blower fan and inspecting the speed regulator and wiring is a recommended first step.
