Function and Fitment
The control module regulates the blower motor speed by controlling current to the fan motor, enabling the HVAC unit to select multiple fan speeds and maintain stable airflow. It is used on a range of Citroën and Peugeot models where Valeo electronics are fitted; Peugeot 308 is a common application. Customers commonly search using the product codes listed above to confirm fitment.
Replacement Procedure
- Disconnect the battery before starting work to prevent short circuits and protect vehicle electronics.
- Access the blower motor area (typically under the glovebox or under the dash on the passenger side). Remove trim panels as required.
- Locate the blower motor control module on or near the blower housing, unplug the electrical connector and remove the retaining screws or clips.
- Fit the new module, secure fasteners, reconnect the electrical connector and reassemble the interior panels.
- Reconnect the battery and verify all fan speed settings and HVAC functions on the vehicle. Check for abnormal noises or failures at each speed.
Installation Recommendations
- Always Disconnect The Battery Before Disassembly.
- Inspect Connector Pins For Corrosion Or Damage And Clean Before Reconnection.
- Ensure The Blower Housing Is Free Of Debris And That The Cabin Air Filter Is Clean To Reduce Load On The Motor And Regulator.
- Use Dielectric Grease On Electrical Connectors If Appropriate To Reduce Moisture Ingress.
- Follow Manufacturer Service Manual For Access Procedures And Fastener Torque Values.
Common Causes Of Failure
- Thermal Stress And Overheating Of Electronic Components Due To High Fan Loads Or Restricted Airflow.
- Corrosion Or Moisture Ingress Into Connectors And PCB Causing Intermittent Or Permanent Failure.
- Electrical Surges Or Short Circuits Upstream (Blower Motor Problems, Faulty Resistors Or Wiring Issues).
- Mechanical Wear On The Blower Motor (Worn Brushes Or Bearings) Increasing Current Draw And Stressing The Regulator.
- Debris And Blocked Cabin Filters Causing Increased Motor Load And Premature Regulator Failure.
Replacing the blower motor control module at the first sign of erratic fan speeds, loss of certain speed settings, or burning smells prevents further damage to the blower motor and HVAC electronics. Suitable for workshops and skilled DIY mechanics who can access the blower housing and follow safe electrical work practices.
