Description
Overview
High-quality used heater blower fan designed for the Citroën C4 Picasso first generation. This left-rear heater fan restores heating performance and cabin airflow, ensuring passenger comfort during colder months. It is commonly referenced by OE part numbers and sought after by professional mechanics and DIY enthusiasts repairing PSA vehicles.
Key Functions
The blower fan circulates warm air from the heater core into the cabin. Proper operation supports interior comfort and helps maintain efficient defogging and demisting of windows. If the blower underperforms, airflow is reduced and cabin heating and ventilation are compromised.
Common Failure Modes and Causes
- Wear of motor brushes or bearings leading to noisy operation or complete stoppage.
- Accumulation of debris or trapped objects that impede the fan wheel.
- Electrical issues such as poor connections, blown fuses, or a failed speed regulator/resistor.
- Moisture ingress causing corrosion and accelerated wear.
Replacement And Installation Notes
Installation is straightforward for an experienced technician or competent DIYer. Basic procedure: disconnect the vehicle battery, remove the relevant interior trim or access panel, disconnect the electrical connector, unfasten the mounting screws, extract the old blower unit and install the replacement. Reconnect the wiring and test all blower speeds before reassembling trim. Always observe basic safety precautions and, where applicable, consult a repair manual for vehicle-specific access points on the C4 Picasso.
Maintenance Tips
- Inspect the blower wheel for debris and clean periodically to prolong life.
- Check the blower resistor/speed regulator and fuses when diagnosing intermittent speeds.
- Lubrication is not typically required for sealed motors; replace if bearings are worn or noisy.
Accessories
The speed regulator (blower resistor/speed control module) is not included and can be purchased separately to restore full speed control when required.
