Installation Recommendations

Follow these general steps as a guideline. Always consult the vehicle manufacturer’s repair manual for exact procedures and torque settings.

• Disconnect the negative battery terminal before starting work to avoid short circuits and protect electronic modules.
• Gain access to the blower unit — typically located behind the glove box or under the right-hand side of the dashboard. Remove trim panels or the glove box as required.
• Unplug the electrical connector and any harness clips. If the blower uses a separate speed regulator or resistor, note its location and condition; the regulator may be replaced separately.
• Unscrew the mounting fasteners securing the blower housing and remove the old unit. Compare connectors and mounting points to ensure correct fitment.
• Install the new blower, secure fasteners, reconnect the electrical connector and reassemble trim. Reconnect the battery and test all blower speeds and HVAC functions before finishing.
• If blower speeds do not operate correctly after installation, check the blower resistor/speed regulator, fuses, and wiring for continuity.

Why This Part Fails

• Mechanical Wear: Bearings and motor brushes degrade over time, causing noise, reduced airflow or complete failure.
• Debris Ingress: Leaves, dust and other debris drawn into the HVAC intake can jam the fan or damage the wheel.
• Moisture And Corrosion: Water ingress from blocked drains or leaks can corrode electrical connections or the motor housing.
• Electrical Faults: Failed capacitors, worn commutator segments or connector problems can interrupt power to the motor.

Practical Tips

• Check and clear HVAC drains and cabin intake areas to reduce debris and moisture reaching the blower.
• When replacing a noisy or failing blower, inspect the resistor/speed regulator and fuses; these are common secondary failure points.
• Keep replacement product codes (9650872480, 6441X5) at hand when ordering to speed up parts lookup.

Technical Information

• Manufacturer: Citroën (Stellantis)
• Model: Citroën C4 Picasso (1st Generation), Citroën Grand C4 Picasso (1st Generation)
• Product Codes: 9688094880, 6441X5
• Other Numbers: 9650872480
• Position: Right Rear (Passenger Compartment Blower)
• Function: Provides forced air circulation for heating and ventilation to the rear cabin; works together with the HVAC unit and heater core.

Installation Recommendations

• Disconnect the battery before starting work to avoid short circuits and to protect vehicle electronics.
• Access the blower by removing the necessary trim panels in the rear passenger area or behind the glovebox depending on vehicle layout; keep fasteners and clips organized.
• Unplug the electrical connector and remove the retaining screws or clips holding the blower housing.
• Replace the blower unit and reconnect the electrical plug. If the fan speed is controlled by a separate regulator, install or test the regulator as well.
• Reassemble trim panels and reconnect the battery. Test all blower speeds and listen for abnormal noise or vibration before finalizing installation.
• Use basic hand tools; in confined spaces a small ratchet and trim tools speed up the job. For full safety follow manufacturer repair procedures.

Why This Part Fails

• Wear Of Internal Brushes Or Bearings — The most common reason for blower motor failure is mechanical wear causing noise, reduced speed, or seized rotor.
• Debris And Foreign Objects — Leaves or small debris drawn into the intake can damage the fan blades or obstruct rotation.
• Water Ingress Or Corrosion — Moisture reaching the motor can cause corrosion and electrical faults.
• Overheating From Blocked Cabin Filter — A clogged cabin filter increases motor load and can shorten service life.
• Faulty Speed Regulator — Intermittent operation or loss of some fan speeds can result from a failing regulator; this component is often replaced separately.

Maintenance And Service Tips

• Check And Replace Cabin Filter Regularly To Reduce Contaminants Entering The Blower.
• Inspect For Debris And Clean The Blower Intake During Routine Service.
• If The Motor Is Noisy Or Intermittent, Inspect Brushes/Bearings And The Speed Regulator Before Replacing Other HVAC Components.
• When Replacing This Unit, Compare Mounting Points And Electrical Connector To Ensure Direct Fit.
