Description
Overview
Used Heater Blower Fan, left rear position, designed for Citroën C4 Picasso (first generation). This blower motor forces warm air from the heater matrix into the passenger compartment to maintain interior comfort and demist windows. It is a practical replacement for workshop technicians and competent DIYers seeking an affordable, direct-fit component.
Function And Symptoms Of Failure
The blower motor circulates air through the heating and ventilation system. Common symptoms indicating the blower needs replacement include reduced airflow at all fan speeds, unusual grinding or rattling noises from the dash area, intermittent operation, or complete loss of blower function. Failures are typically caused by worn bearings, degraded motor brushes, debris ingress, or electrical issues in the connector or speed regulator.
Why This Part May Fail
- Mechanical wear: Bearings and brushes wear over time, producing noise or loss of rotation.
- Contamination: Leaves, dust or water can enter the blower housing, causing imbalance and premature failure.
- Electrical faults: Corroded connectors, damaged wiring or a faulty speed regulator can prevent proper operation.
Fitment And Compatibility
Intended for the Citroën C4 Picasso first generation. Commonly referenced by PSA part numbers 9688094980, 6441X4 and cross-referenced with 9650872580. Always verify the part numbers against your vehicle VIN or the existing unit before ordering to ensure correct fitment.
Replacement Guidance (General)
Typical replacement requires moderate workshop skills and basic tools. General steps:
- Disconnect the vehicle battery for safety.
- Access the blower unit via the lower dash or glovebox area on the passenger side; in some cases remove trim panels to reach the blower housing.
- Unplug the electrical connector and any harness clips, then remove the mounting screws or fasteners holding the blower assembly.
- Withdraw the blower from its housing, replace with the new unit and reverse the disassembly steps. Reconnect battery and test all fan speeds.
If the fan still operates only at certain speeds or is noisy after replacement, check the speed regulator/resistor and connectors. The speed regulator is not included and is available separately.
Benefits For Mechanics And DIYers
This direct-fit blower offers a cost-effective repair option compared to new OE units while retaining the original fit and function. It is ideal for workshops performing routine climate system repairs and for car owners performing self-maintenance who require clear fitment references by part number.
