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.
Suitable For
Technicians and DIY enthusiasts working on Citroën C4 Picasso and Grand Picasso first generation vehicles who require a right-rear heater blower fan replacement. Ideal for restoring full HVAC performance when the original blower shows noise, reduced airflow or intermittent operation.
