Description
Overview
This fan regulator (blower motor resistor) with part number 6441V8 is designed for PSA group vehicles and provides reliable control of HVAC fan speeds in Citroën and Peugeot cars. It is a direct replacement part intended for technicians and DIY enthusiasts who need to restore precise blower operation.
Function And Benefits
The component regulates current to the blower motor, creating multiple fan speed steps for the vehicle heating, ventilation and air conditioning system. A correctly functioning regulator ensures stable cabin airflow, smooth speed transitions and prevents excessive current draw on the blower motor circuit.
Common Symptoms Of Failure
Typical signs that the fan regulator is failing include loss of some or all fan speeds, fan only working on the highest speed, intermittent blower operation, unusual noises from the blower area or a burning smell in the dash. Failures usually result from overheating, corrosion of electrical contacts, moisture ingress or increased load from a failing blower motor.
Installation Notes
Replacement can usually be performed by a qualified mechanic or experienced DIYer. Typical steps:
- Disconnect the negative battery terminal before work.
- Access the blower motor housing (often located under the glovebox or behind the lower dash panel).
- Unplug the electrical connector from the resistor/regulator and remove the mounting screws or clips.
- Fit the new regulator, secure fasteners to the manufacturer’s specification and reconnect the electrical plug.
- Reconnect the battery and verify all fan speeds and HVAC functions operate correctly.
Always check the vehicle service manual for model-specific instructions and safety precautions. If the new regulator fails shortly after replacement, inspect the blower motor for excessive current draw and check wiring and connectors for damage or corrosion.
