The interior blower — also called the heater blower motor — circulates air through the cabin heating, ventilation, and air conditioning system. When it fails, you lose demisting, heating, and conditioned airflow, making the cabin uncomfortable and reducing visibility in cold or wet weather. Faults range from a completely dead blower to a motor that only works on certain speed settings due to a failed blower resistor. Valeo, Mahle, and Hella supply replacement blower motors and resistors for a comprehensive range of vehicles. The blower is usually accessed from behind the glovebox or under the dashboard — a straightforward job on most platforms.
Before replacing the motor, identify whether the fault is in the motor itself, the resistor pack, or the control switch. This avoids unnecessary parts purchases.
The resistor pack controls fan speed by varying the voltage supplied to the motor. It is far more commonly replaced than the motor itself. Always check the resistor first — it is usually clipped into the blower housing and takes minutes to swap.
Disconnect the battery before starting to avoid accidental airbag deployment. Remove the glovebox or lower dashboard trim to access the blower housing. Unclip the electrical connector, remove the retaining screws, and withdraw the motor. Transfer any foam seals to the new unit and reverse the procedure.
