Description
Overview
The Heater Fan/Blower Motor for Peugeot 406 & 607 provides reliable cabin airflow for heating and air conditioning systems. Commonly referenced by part numbers 659963H and 6441K9, this unit is a direct-fit replacement suited to professional workshops and experienced DIY mechanics.
Function And Typical Failures
The blower motor forces air through the HVAC system into the cabin. Typical failure modes include worn brushes, bearing seizure, contamination from dust or moisture, and electrical connector or blower resistor faults. Symptoms include noisy operation, reduced airflow, intermittent function, or complete stop.
Replacement And Maintenance
Replacement is usually performed from under the dash or behind the glovebox. Typical steps: disconnect the battery, remove trim or glovebox to access the blower housing, disconnect the electrical connector, unbolt the blower housing, remove the old unit and fit the new fan, then reconnect wiring and test all speed settings. While servicing, inspect the blower resistor, associated fuses and the cabin pollen filter for contamination.
Durability And Causes Of Failure
Service life depends on usage and environment; many blower motors remain serviceable for 8–15 years. Failures commonly result from normal wear (brushes and bearings), debris ingress, water intrusion, or electrical issues. Regular cabin filter changes and keeping the HVAC intake clear can extend service life.
