Description
Overview
This used heater fan (blower motor) is a direct-fit replacement for the Citroën C4 Picasso first generation. Positioned on the left-rear side of the HVAC housing, it restores cabin heating performance and reliable air circulation. The unit is a popular choice among professional mechanics and experienced DIY enthusiasts looking for an OEM-compatible solution.
Function & Compatibility
The blower motor forces heated or cooled air through the vehicle ventilation ducts and cabin vents. Proper operation ensures consistent cabin temperature and supports the vehicle’s climate control system. This fan is compatible with Citroën C4 Picasso (first generation) models and is commonly referenced by the product codes 9650872580, 9688094980 and 6441X4 for parts lookup.
Speed Regulator
The speed regulator (blower motor resistor or electronic regulator) is not included with the fan and can be purchased separately if required. Replacing the regulator together with the fan often restores full multi-speed control and prevents intermittent operation caused by a failed resistor or connector corrosion.
Common Failure Modes & Maintenance
Blower motors typically fail due to bearing wear, contamination of the fan impeller, electrical faults such as burned windings, or issues with the speed regulator and connectors. Symptoms include unusual noises, reduced airflow, or loss of specific speed settings. Regular inspection and cleaning of the intake area can extend service life and reduce the risk of premature failure.
Installation Guidance
Installation is straightforward for a qualified technician or an experienced DIYer. Typical steps include disconnecting the battery, removing the glovebox or access panel to reach the HVAC housing, unplugging the electrical connector, removing mounting screws, replacing the fan assembly, and reassembling in reverse order. Always verify correct operation of all blower speeds after installation.
