Information
Heater blower motor and fan (in bulkhead).
The blower motor with integrated fan, designed for the heating and ventilation system of early Porsche 911, 912 and 914. Its function is to drive airflow through the heater box, evaporator or heat exchanger, and distribute conditioned air into the cabin - ensuring comfort, defrosting, and proper climate control. Built to original factory specifications, it ensures quiet, robust airflow, restores cabin comfort and supports reliable heating, ventilation and defrost performance.
Fits:
Porsche 911 1965 - 1989
Porsche 912 1969
Porsche 914 1970 - 1976
Diagram ref no 11
• Position on Vehicle: Mounted in the front bulkhead/heater box area ('centre of bulkhead') behind the dashboard or in the ventilation/heating assembly.
• Cross-Reference / Alternative Numbers: 911 571 320 32 (replaces 901 571 320 32)
• Applications: Ideal when the original blower motor shows reduced airflow, increased noise, or erratic operation - or when restoring the HVAC system of a classic Porsche to full performance.
The blower motor is a core component of the HVAC system in your Porsche: it supplies the airflow needed for heating, cooling and ventilation. When the motor or fan wheel deteriorates, you may experience weak airflow, increased noise, erratic vent output or failed defrosting—compromising comfort and safety. Replacing it with a quality OE-Match unit restores proper airflow distribution, ensures the longevity of other HVAC components and maintains the premium experience your Porsche deserves.
When and why to replace:
• Noticeable reduction in airflow or weak ventilation from vents.
• Unusual noises (whine, rattle, vibration) coming from the blower or vents.
• Blower fails to operate or only works intermittently.
• Visible damage, wear or corrosion in the blower housing or fan.
• During or after restoration of the heating/ventilation system of a classic Porsche.

Air conditioning blower regulator.
Genuine Porsche HVAC blower motor regulator (also known as a blower resistor or control unit). It is an original equipment component manufactured to Porsche factory specifications and designed to precisely control the speed of the interior blower motor within the vehicle’s heating, ventilation, and air conditioning (HVAC) system.

The blower motor regulator controls fan speed variation in response to climate control settings. It allows the HVAC system to smoothly adjust airflow from low to high speeds, ensuring consistent cabin temperature control and passenger comfort. When functioning correctly, it enables quiet, responsive, and efficient blower operation.
Function:
• Fan Speed Control: Regulates the electrical load to the blower motor for smooth multi-speed operation.
• Climate Comfort Management: Ensures accurate airflow delivery based on driver and passenger HVAC settings.
• System Protection: Prevents electrical overload of the blower motor by maintaining controlled power delivery.
A failing blower motor regulator can cause loss of fan speed control, intermittent blower operation, or complete HVAC failure. Common symptoms include the blower only working at one speed (often maximum) or not operating at all. Replacing the unit restores factory-correct airflow control, reliability, and cabin comfort while ensuring full system compatibility.
Replace the blower motor regulator if you experience:
• Blower fan stuck on one speed
• No airflow from vents despite HVAC settings
• Intermittent or unpredictable fan operation
• HVAC system faults related to blower control

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
