Description
Overview
This Fan Speed Regulator (part number 6450EP) is designed for PSA vehicles and is commonly used on Citroën Xsara Picasso and Peugeot 206 models. The unit controls blower motor speeds in the HVAC system, allowing smooth selection of fan intensities. It is a practical replacement part for professional mechanics and do-it-yourself car owners who often search by product code.
Function And Typical Failure Modes
The regulator governs the blower motor speed by varying the electrical control to the fan motor (voltage/resistance modulation). Common symptoms of a failing regulator include loss of some or all fan speeds, fan stuck on one speed, or intermittent operation. Typical causes of failure are corrosion from moisture ingress, thermal stress and overheating, worn electrical contacts, or damage to the connector and wiring.
Fitment And Compatibility
Fitment is specified for Citroën Xsara Picasso and Peugeot 206 when referenced by part number 6450EP. Always verify compatibility with your vehicle by checking the part number against your VIN or the existing part before ordering. Many customers locate this part by searching for the code 6450EP.
Replacement Guide
Typical replacement steps for experienced mechanics and competent DIYers:
- Disconnect the negative battery terminal to prevent electrical shorting.
- Access the blower motor housing—on many PSA cars this requires removing or lowering the glovebox or accessing from under the dash on the passenger side.
- Locate the fan speed regulator on the blower housing; unplug the electrical connector and remove the mounting screws or clips.
- Install the new regulator, secure fasteners, reconnect the electrical connector and test all fan speeds before full reassembly.
Practical tips: inspect the blower motor and connector for signs of overheating or corrosion; apply a small amount of dielectric grease to connectors if appropriate; replace mounting screws if corroded. If the new regulator fails quickly, check the blower motor for excessive current draw which can damage regulators.
