Description
Heater blower with regulator for Citroën C4 Picasso first generation
High-quality heater blower with integrated regulator designed for Citroën/Peugeot applications. This direct-replacement blower motor assembly restores reliable cabin airflow and precise fan-speed control for HVAC systems on the Citroën C4 Picasso (first generation). Ideal for professional workshops and DIY mechanics who need a durable motor and the correct regulator for smooth, noise-free operation across all fan settings. Supplied with common OEM reference numbers used across Stellantis parts catalogs to simplify identification.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën C4 Picasso (First Generation)
- Product Codes: 5E2228000, 9654652480
- Additional Numbers: 6441W8, 6441W9
Function And Application
The heater blower is responsible for moving air through the HVAC evaporator and heater core into the passenger cabin. The integrated regulator controls fan speeds by varying motor power, enabling low to high airflow settings and ensuring comfort and effective defogging. This unit is intended primarily for the passenger compartment HVAC system of the Citroën C4 Picasso first-generation vehicles and equivalent Stellantis applications carrying the listed part numbers.
Installation Recommendations
- Always disconnect the battery before starting work to avoid short circuits and protect electrical components.
- Access is typically from below the dashboard on the passenger side; removal of the glovebox or under-dash panels may be required to reach the blower housing.
- Disconnect the electrical connector and any ducting or fasteners securing the blower housing. Remove mounting screws/clips and extract the old unit.
- When fitting the replacement, ensure correct orientation of the motor and regulator, secure all fasteners, and reconnect the electrical connector firmly.
- After installation, verify operation across all fan speeds and check for abnormal noise or vibration. Replace the cabin air filter if heavily contaminated to prevent premature motor overload.
- Handle electrical connectors and the regulator electronics with care to avoid damage from static or impact.
Most Common Failure Reasons
- Brush And Bearing Wear: Over time brushes wear down and bearings can seize, causing reduced performance, noise, or complete motor failure.
- Regulator/Resistor Damage: Thermal stress and electrical overload can degrade the regulator components, resulting in loss of speed control or single-speed operation.
- Contamination And Moisture: Accumulation of dust, debris, or moisture accelerates wear and can cause short circuits or corrosion of contacts.
- Blocked Airflow: Clogged cabin filters or debris in the ducts increase motor load and shorten service life.
- Typical Service Life: Depending on usage and environment, blower motors commonly last several years; heavy use or harsh conditions can require replacement after approximately 8–15 years or sooner.
Why Choose This Part
This blower motor with regulator is specified to match OEM electrical and mechanical interfaces associated with the listed part numbers, making it a practical option for repairs where OEM references match. It provides reliable fan control and is suitable for mechanics who need a direct-fit solution to restore HVAC functionality and cabin comfort.
