Function And Symptoms

The regulator (blower motor resistor) governs the blower motor speeds of the vehicle HVAC system. When it fails, common symptoms include blower operating on a single speed (usually high only), intermittent fan operation, complete loss of blower function, or a noticeable burning smell near the glovebox area. Failure affects cabin heating, ventilation and demisting efficiency.

Installation Recommendations

1. Park Vehicle On A Level Surface And Switch Off Ignition. For Safety, Disconnect The Negative Battery Terminal Before Working On Electrical Components.
2. Access The Resistor Pack—Typically Located Behind The Glovebox Or Under The Dash On The Passenger Side. Remove The Glovebox Or Trim Panels To Reach The Unit.
3. Unplug The Electrical Connector And Unscrew The Mounting Fasteners. Inspect Connector Pins For Corrosion Or Heat Damage.
4. Fit The Replacement Unit, Secure Fasteners, Reconnect The Connector And Reassemble Panels. Reconnect Battery And Test All Blower Speeds To Confirm Proper Operation.
5. Check And Replace Cabin Air Filter If Heavily Contaminated; Restricted Airflow Is A Common Cause Of Overheating And Premature Regulator Failure.

Most Common Failure Reasons

• Overheating Due To Restricted Airflow From A Clogged Cabin Filter Or Blocked Vents.
• Corrosion Or Poor Contact At The Electrical Connector Causing Voltage Drops And Local Heating.
• Ageing And Thermal Fatigue Of Resistor Elements Or Internal Electronics.
• Water Ingress From Heater Box Or Drain Blockages Leading To Short Circuits Or Corrosion.

Typical Service Life Depends On Vehicle Use And Environmental Conditions, But Failures Are More Likely After Several Years Of Operation, Especially If Cabin Filtration And Ventilation Are Neglected.

Heating and air -conditioning resistor/resistor for Citroën and Peugeot with PSA 6450NV ensures continuous fan speed control in the cabin. It is an original Valeo solution, designed for reliable cooperation with the electronics of the car and correct cooling/heating performance. Especially suitable for the Citroën Berlingo and Peugeot Partner (according to the specific equipment).

Typical manifestations of defects of this part: The fan works only to the highest speed, does not spin at all, the speed varies or the fan spontaneously turns off. The cause is the thermal stress of the module, increased consumption of worn fan motor or clogged cabin filter that worsens the air flow.

The mounting is usually fast: the module is located near the heating fan (most often under the dashboard at the passenger). Procedure: Disconnect the battery, remove the bottom cover, disconnect the controller connector, release the screws (often torx), remove the part and fit the replacement. When replacing, we recommend checking the cabin filter status and free operation of the fan itself to prevent the new regulator to prevent repeated overload.

For the correct selection, compare the 6450NV code (often mentioned as 6450 NV or 6450.NV) and the shape/connector of your original part. For these cars, depending on the equipment (manual vs. automatic air conditioning), different types of regulators/resistance are used, so the match number and connector numbers is crucial.

This blower motor regulator (fan speed control) is a direct-fit replacement designed for heating and ventilation systems on a range of Citroën and Peugeot models. Ideal for professional mechanics and competent DIY enthusiasts, the unit restores reliable multi-speed fan control and eliminates symptoms such as loss of selected fan speeds, intermittent operation, or complete blower failure. Frequently searched by part numbers 6441L2, 6441P3 and 6442P3, this module improves comfort and defogging performance when installed correctly.

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: Citroën C2, C3, C5; Peugeot 206, 207, 1007, 406, 607
• Product Codes: 6441L2, 6441P3
• Other Numbers: 6442P3

Function and Application

The regulator controls the blower motor speed by modulating the electrical power supplied to the fan (typically using pulse-width modulation or an electronic resistance stage depending on the system). It is mounted in the HVAC housing near the blower motor or on the air distribution box. Correct operation ensures accurate fan speed selection, efficient cabin heating/cooling and rapid window demisting.

Signs Of Failure

• Blower runs only at one speed (usually high) or does not respond to speed selector changes
• Intermittent blower operation or complete loss of blower
• Clicking noises from under the dash or burning/electrical smell
• Reduced airflow and slower cabin demisting

Why The Part Most Commonly Fails

Failures are usually caused by prolonged thermal stress, dust accumulation, corrosion of connector pins, or excessive current draw from a worn blower motor. Poor ventilation in the HVAC box and water ingress (from clogged drainage or leaks) accelerate degradation of electronic components and solder joints.

Replacement Procedure

Basic replacement steps for a competent mechanic or DIYer:

1. Disconnect the negative battery terminal before starting work to avoid electrical hazards.
2. Access the regulator by removing the glovebox or lower dashboard trim on the passenger side as required for the model.
3. Locate the blower motor housing, unplug the electrical connector, and remove the retaining screws or clips securing the regulator.
4. Install the new unit, secure fasteners, and reconnect the electrical connector.
5. Reconnect the battery, then verify all fan speeds and HVAC functions before final reassembly.

Installation Recommendations

• Always disconnect the battery before removal and follow the vehicle manufacturer’s basic instructions to avoid damage.
• Inspect the blower motor for excessive play or brush wear; a failing motor increases load and shortens regulator life.
• Clean connector pins and HVAC housing; apply a small amount of dielectric grease to connectors to reduce corrosion risk.
• After fitting, verify all speed positions and listen for abnormal noises. If the new regulator fails quickly, re-check the blower motor current draw and ventilation drains for water ingress.

This replacement regulator is suitable for workshop installation and for experienced DIY repairs. Use the listed product codes (6441L2, 6441P3, 6442P3) to confirm match with the vehicle model and year before ordering.

The Valeo Fan Regulator Resistor 6445ZA is an essential component designed specifically for Citroën and Peugeot vehicles, notably the Citroën C1 and Peugeot 107 models. This regulator controls the speed of the cooling fan, enabling efficient heat dissipation from the engine bay to maintain optimal operating temperature.

Function and Importance

The fan regulator resistor manages electrical current to the radiator fan motor, allowing multiple fan speed levels rather than a simple on/off function. Proper fan regulation improves cooling system efficiency, reduces engine overheating risks, and helps maintain passenger comfort by ensuring consistent operation of the vehicle’s climate system.

Common Failure Causes and Replacement

Over time, the resistor may degrade due to electrical wear, heat exposure, or corrosion, which can cause the fan to operate only at full speed or not run at all. Symptoms of failure include unusual fan speeds, engine overheating, or the climate system not performing correctly. Replacing the fan regulator resistor promptly restores proper fan control and prevents potential engine damage.

Installation Notes

Replacing the fan regulator is a straightforward procedure typically requiring access to the cooling fan assembly behind the radiator. Disconnect the battery before starting the replacement to ensure safety. Remove the faulty resistor module and install the new Valeo 6445ZA regulator, reconnecting all electrical connectors securely. It is advisable to check the entire cooling fan circuit for any additional faults during replacement.
