Description
Cooling Fan Motor Resistor for CITROËN PEUGEOT Vehicles
This blower motor resistor (OEM references 9673999880, 1308CL, 9830143880) is designed for Citroën and Peugeot passenger cars. It restores stepped fan-speed control for the heating and ventilation system, ensuring reliable cabin airflow and precise climate control. Suitable for workshop professionals and competent DIY mechanics, the unit is a straightforward replacement part for models such as Citroën C4 and Peugeot 307 and other compatible PSA-platform vehicles. Replacing a faulty resistor typically returns full fan-speed range (low/medium/high) and eliminates symptoms like loss of certain blower speeds, intermittent blower operation, or completely dead fan at select settings.
Technical Information
- Manufacturer: Stellantis / Citroën / Peugeot
- Model: Citroën C4; Peugeot 307
- Product Codes: 9673999880; 1308CL
- Other Numbers: 9830143880
Function And Typical Fault Symptoms
The blower motor resistor provides discrete resistance stages to control the blower motor speed selected from the cabin fan switch. When the resistor fails, common symptoms include loss of one or more fan speeds, blower only working on the highest speed, intermittent operation, or overheating smell from the dashboard.
Why This Part Fails
- Overheating of resistor coils due to high current draw from a worn or obstructed blower motor.
- Corrosion and moisture ingress at the connector or resistor body, especially in older vehicles.
- Electrical contact wear or broken solder joints from thermal cycling and vibration.
- Accumulation of debris in the ventilation system increasing load on the motor.
Installation Recommendations
- Safety First: Always disconnect the battery before starting removal and follow the manufacturer’s procedures to avoid damage to electrical components.
- Access: The resistor is typically located in the HVAC housing near the blower motor—commonly under the glovebox or behind lower dash panels. Remove trim panels as required.
- Disconnect the electrical connector, remove the mounting screws securing the resistor, and carefully extract the old part.
- Inspect the blower motor and connector for signs of excessive wear, corrosion, or melted plastic. Repair or replace the blower motor if it draws excessive current to prevent repeating resistor failures.
- Fit the replacement resistor, secure mounting screws, reconnect the electrical plug, reassemble panels, reconnect the battery, and verify all fan speeds operate correctly.
- If fan speeds remain abnormal after installation, check wiring, fuses, and the blower motor for faults before replacing the resistor again.
Maintenance Tips
- Keep the cabin air filter clean to reduce dust and debris buildup that can increase blower load.
- Periodically inspect the blower motor connector and resistor for corrosion or heat damage.
- Address unusual noises or reduced airflow promptly—these can indicate impending resistor or motor failure.
