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.

• 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.

OEMatch Blower Motors & Fans — Fit, Function, Confidence
Blower motors and fan assemblies move air through a Porsche’s heating and air‑conditioning ducts to support cabin comfort, demisting and ventilation. OEMatch supplies replacement blower motors and fan units chosen to help restore reliable airflow and HVAC response for Porsche models, useful when servicing, restoring or upgrading climate control systems.
Available Types
- Replacement blower motor units
- Fan and wheel assemblies
- Blower motor resistor and speed‑control modules
- Complete blower modules with housing and mounting
Understanding OEMatch Blower Motors & Fans
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original blower motors & fans.
OE (Original Equipment) refers to parts matching original specifications for the blower motors & fans and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM blower motors & fans engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Blower motors drive the fan that circulates air through the evaporator, heater core and cabin vents. Correct selection ensures appropriate airflow at each speed setting, quiet running and compatibility with a vehicle’s mounting points and electrical controls. OEMatch provides a broad selection of items for Porsche HVAC applications and continues to extend its range to cover model-specific needs.
Benefits Include
- Restores strong, consistent airflow for heating and cooling
- Reduces noise and vibration from worn components
- Helps prevent windscreen fogging and improves cabin comfort
Why Blower Motors & Fans Wear and Fail
- Worn brushes or bearings causing slow or noisy operation
- Debris or contamination obstructing the fan wheel
- Electrical faults such as failed connectors, resistors or motor windings
- Moisture ingress leading to corrosion or short circuits
The Importance of Replacing with OEMatch Blower Motors & Fans
Replacing a failing blower motor or fan assembly restores effective ventilation and ensures the HVAC system can deliver the temperatures and airflow required for comfort and safety in a Porsche. Appropriate replacements reduce the risk of intermittent operation, eliminate distracting noise, and support clear visibility by improving demist and defrost performance.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Designed to fit original mounting points and clearances
- Compatible with factory control systems and common sensor interfaces
