This OE Match blower motor resistor (also known as a blower control unit or HVAC blower regulator) is engineered to meet or match the original Porsche specifications for reliable airflow regulation in the vehicle’s HVAC system. It’s an ideal replacement when the original unit fails or when restoring climate control performance.

The blower motor resistor enables variable control of the HVAC blower motor speed, typically by adjusting resistance in the circuit that powers the blower. When functioning correctly, it lets your HVAC system modulate airflow through the vents across multiple fan speeds - from gentle circulation to full fan power. Without a working resistor, the blower may only operate at one speed (usually high), or not at all.

A failing blower motor resistor can cause inconsistent HVAC fan performance, reduced airflow, inability to adjust fan speed, or complete blower failure - diminishing cabin comfort and making climate control unpredictable. Replacing it with an OE Match quality unit restores proper fan speed control and helps maintain reliable interior climate performance without the cost of a full OEM part.

Replace this part if you observe any of the following symptoms:
•  HVAC blower only works at one fan speed (e.g., full speed)
•  Inconsistent or weak airflow from vents
•  No blower function at certain fan settings
•  Intermittent or failed blower operation
