Description
Reliable replacement heater fan for Citroën C4 Picasso (first generation). This unit is a used rear-left heater blower motor intended for mechanics and DIY enthusiasts who need to restore effective cabin heating and consistent airflow. It fits original PSA mounting and electrical connections for the listed part numbers.
Function: The heater fan (blower motor) pushes warm air from the heater core into the passenger compartment and distributes airflow across vents. Proper blower operation is essential for rapid cabin warm-up, demisting the windshield and maintaining passenger comfort.
Common Failure Modes: Blower motors typically fail due to bearing wear, motor winding degradation, foreign debris lodged in the fan wheel, or electrical issues such as corroded connectors or a faulty speed regulator/resistor. Signs of failure include unusual noise, reduced airflow, intermittent operation or complete stop.
Replacement And Installation Notes: Before starting, disconnect the vehicle battery. Access to the rear-left heater fan on the first-generation C4 Picasso usually requires removal of interior trim panels or the glovebox area to reach the blower housing. Remove electrical connectors and fasteners securing the unit, extract the old fan module and install the replacement in reverse order. Verify connector condition, clean ducting of debris and test all fan speeds after installation. If the fan still operates only on certain speeds or not at all, the speed regulator/resistor may need replacement; this regulator is sold separately.
