• Replace the cabin air filter and clean the blower housing to prevent premature wear from debris.
• Check related components (blower resistor/module, fuses, and connectors) when diagnosing partial or intermittent operation.
• Use appropriate tools (screwdrivers, Torx/metric sockets) and avoid forcing connectors to prevent damage.

Common Failure Causes

Heater blower motors typically fail for mechanical or electrical reasons. The most frequent issues are worn bearings or motor brushes, contamination by leaves/debris or water, and overheating from restricted airflow (for example, a clogged cabin filter). Electrical causes include faulty blower resistors or poor connector contacts which can result in loss of some fan speeds or intermittent operation. Symptoms include no airflow at any speed, fan working only on certain speeds, grinding or rattling noises, or a burning smell.

Diagnostics Tips

• If the fan does not run at any speed, check fuses and the blower relay first.
• When the fan works on only one speed, suspect the blower resistor or its connectors.
• Unusual noises often indicate worn bearings or a damaged fan wheel—inspect and replace the motor assembly if necessary.
• After replacement, verify airflow and noise levels at each speed setting to confirm correct installation.

• If you encounter intermittent operation or faults after replacement, recheck connectors and grounds before further diagnostics.

Why This Part Most Commonly Fails

The blower motor typically fails due to normal wear and tear of internal components and environmental factors:

• Worn Brushes Or Bearings: Over time, brushes wear down and bearings degrade, causing reduced performance, increased noise or seizure.
• Debris And Leaves: Foreign objects entering the HVAC intake can block the fan or damage the impeller.
• Water Ingress: Blocked drain channels or leaks can allow moisture to reach the motor, causing corrosion or electrical faults.
• Overheating From Excess Load: A clogged cabin filter or restricted airflow increases motor load and accelerates wear.

Common symptoms of a failing blower include reduced airflow at all fan speeds, loud or unusual noises from the dash, intermittent operation, or complete loss of fan function.

Search And Identification

This blower is commonly listed under part numbers T3953003 and 6441CP. Including these codes in searches (plus model identifiers Peugeot 3008 T84 / 5008 T87) improves chances of finding the correct replacement quickly.

This used heater blower (blower motor) is a direct-fit unit for Peugeot 206 and 206+ vehicles and is commonly referenced under part number 6441J8. Ideal for professional workshops and DIY mechanics, it restores cabin airflow for heating and air conditioning systems and helps maintain comfort and defrost performance. The blower is a frequent replacement item when owners report weak air flow, unusual noises from the HVAC area, or intermittent operation.

• Intermittent fan operation or no fan at all despite the HVAC controls appearing functional.
• Unusual buzzing or loss of smooth fan speed transitions.
• Electrical smell or visible heat damage at the connector or module.

Common Causes Of Failure

The most frequent reasons for control module failure are thermal stress from high current demand, water or moisture ingress into connectors, corrosion of electrical contacts, and damage caused by a failing blower motor that draws excessive current. Short circuits in the blower wiring or repeated overheating during heavy use accelerate degradation of electronic components.

Replacement And Installation Recommendations

Follow these practical steps and recommendations to ensure a safe and durable replacement:

• Disconnect the vehicle battery before any work to avoid short circuits and protect the electronics.
• Access the module—on these models the blower control module is typically mounted on or near the HVAC housing behind the glovebox or lower dash. Remove the glovebox or lower trim as required to reach the unit.
• Unplug the electrical connector and remove the fasteners securing the module. Fit the new module in the same orientation and secure it with the original fasteners.
• Inspect the blower motor and wiring before final assembly: measure motor current and check for worn brushes or seized bearings. If the motor draws excessive current, it can quickly damage a new control module.
• Apply dielectric grease to connectors to reduce the risk of corrosion and ensure firm pin engagement.
• After installation, reconnect the battery and test all fan speeds and HVAC modes. Verify there are no error messages and that airflow changes smoothly across settings.

Why Replacing The Module Alone May Not Be Enough

If the underlying cause is a failing blower motor, degraded wiring or a shorted connector, simply fitting a new control module can result in repeated failures. Always check the blower motor, fuse, and wiring harness for excessive current draw, heat damage or corrosion before installing the replacement module.

This Heater Fan Regulator (part number 644178) is a direct-fit electrical component for a range of older Citroën and Peugeot models. It controls the blower motor speeds of the heating and ventilation system, restoring regulated airflow and reliable climate control. Designed for professional workshops and experienced DIY mechanics, this unit is a practical replacement when low or missing fan speeds, intermittent blower operation, or visible damage to the resistor pack is diagnosed. Supplied for a wide variety of models, it increases serviceability of older Stellantis vehicles and helps return comfortable cabin ventilation quickly.

Technical Information

• Manufacturer: Stellantis / Citroën / Peugeot
• Model: Citroën AX, Saxo, Xantia, XM, Berlingo, Xsara, ZX; Peugeot 106, 405, 406, 605, Partner
• Product Codes: 644178
• Other Numbers: Not Available

Function And Symptoms

The regulator (blower resistor) modulates current to the heater blower motor to provide selectable fan speeds. Typical symptoms of a failing unit include loss of one or more blower speeds (often only high speed remains), intermittent blower operation, humming or burning odor from the dash, or visible heat damage/corrosion on the resistor module. Replacing the regulator usually restores all fan speeds when the blower motor itself is serviceable.

How It Is Replaced

Typical replacement steps (vehicle-specific details may vary):

• Disconnect the negative battery terminal to prevent short circuits when working on electrical connectors.
• Access The Regulator: It is commonly mounted in the heater box near the blower motor. On many models this is reachable from the passenger footwell after removing the glovebox or an access panel.
• Unplug The Electrical Connector and remove the mounting screws securing the resistor pack to the heater housing.
• Replace The Unit And Reassemble: Fit the new regulator, secure screws, reconnect the plug and battery, then test all blower speeds and functions.
• Verify Operation: Test fan speeds at each setting and check for unusual noises or overheating. If only high speed works after replacement, inspect the blower motor for excessive current draw or worn brushes.

Installation Recommendations

• Use Basic Electrical Safety: Disconnect the battery before starting work and avoid pulling on wiring — release connector clips carefully.
• Inspect The Blower Motor And Connectors: A failing blower motor can overload and rapidly damage a new resistor; measure motor current if possible.
• Clean Contact Surfaces: Remove corrosion from connector pins and apply a small amount of dielectric grease to protect against moisture.
• Check Mounting Seals: Ensure the heater box seals are intact to prevent water ingress that can corrode the resistor in the future.

Why This Part Fails Most Often

• Overheating: Resistor tracks can burn out with age or when the blower motor draws excessive current.
• Corrosion And Moisture Ingress: Water or high humidity in the heater box causes connector and resistor failure.
• Electrical Problems: Loose connectors, shorts, or poor grounding increase heat and accelerate wear.
• Blower Motor Wear: Worn brushes or a partially seized motor increase current draw and shorten the resistor’s lifespan.

Additional Diagnostic Tips

Before replacing the regulator, check for:

• Voltage At The Connector With The Fan Switched On (compare to battery voltage).
• Excessive Current Draw From The Blower Motor—an indicator the motor may be failing.
• Visible Damage Or Burn Marks On The Old Resistor Pack.
• Intermittent Operation Caused By Loose Connectors—clean and reseat before replacement.

This replacement part is aimed at professional mechanics and competent DIYers familiar with electrical diagnostics and safe workshop practices. Proper inspection of the blower motor and connectors will maximize the lifespan of the new regulator and avoid repeated failures.
