Function And Common Faults
The heater blower fan circulates air through the vehicle heater core and HVAC ducting, providing cabin heating, ventilation and helping to demist windows. Typical failure modes include worn bearings, brush or commutator wear in the motor, contamination from leaves or debris, and electrical connector or wiring faults. Symptoms of a failing blower include reduced or intermittent airflow, unusual noise from the ventilation area, or total loss of fan operation. Failures are more common in vehicles with high mileage, heavy use of ventilation, or where external debris can enter the intake.
Replacement Guidance
Replacement is straightforward for technicians familiar with PSA HVAC layouts. General steps:
- Disconnect the vehicle battery before starting electrical work.
- Access the blower housing (commonly located under the glovebox or behind the lower dash panel).
- Remove any trim or covers, unplug the electrical connector and remove retaining screws or clips.
- Extract the old blower assembly, fit the new Valeo unit, reconnect the connector and secure all fasteners.
- Reconnect the battery and test blower speeds and operation across settings.
If you are unsure about access panels or wiring, consult a service manual for the specific model or seek assistance from a qualified technician.
Durability And Maintenance
Service life depends on use and environment. Regularly clearing intake areas of leaves and debris and ensuring cabin filters are replaced on schedule reduces strain on the blower motor. Electrical checks for connectors and fuses can prevent premature failures. When diagnosing poor airflow, always rule out clogged cabin filters and duct obstructions before replacing the blower motor.
