This OE match heater blower fan is a direct replacement for the original Porsche component used in the heating system of air-cooled 911 models. Housed in a durable steel casing, it is mounted in the engine bay and forms a key part of the vehicle’s heating and ventilation system.
Fits:
Porsche 911 3.2L 1984-89
Porsche 965 Turbo 3.3L / 3.6L 1991-94

This blower fan forces warm air generated by the engine’s heat exchangers into the cabin heating ducts. It improves airflow, helping the interior heat up more quickly and maintain consistent cabin temperature, especially at lower engine speeds.
Function
• Circulates heated air from heat exchangers to cabin
• Enhances heating performance at low engine speeds
• Maintains consistent airflow through HVAC system
• Supports demisting and defrosting functions
• Operates within engine compartment under high heat conditions
A failing heater blower can result in weak or inconsistent cabin heating, poor demisting, and reduced comfort. Over time, motors can wear out or fail due to heat and age. Replacing the blower restores proper airflow, ensures effective heating, and maintains safe visibility in cold or damp conditions.
When to replace
• Weak or no airflow from heating system
• Cabin takes too long to heat up
• Unusual noise from blower motor
• Heater not functioning at low engine speeds
• During heating system overhaul or restoration

This harness set is designed to protect the footwell blowers of the 911 Carrera 3.2 with an inline fuse.
Models from 1984 until April 1986 lacked fusing for the footwell blowers. The fan motors, often prone to failure due to bearing issues, could seize and potentially overheat, leading to damage.
Our inline fuse set offers a direct solution, featuring a 10A inline LED fuse. In the event of a motor short, the fuse will blow and the LED will illuminate, safeguarding your valuable trunk harness.

OEMatch Heater blowers — Fit, Function, Confidence
Heater blowers drive warm air through the heater core and vents, supporting demisting, defrosting and cabin comfort for Porsche models. OEMatch supplies replacement blower motors and assemblies for Porsche applications, drawing on a wide catalogue of parts and over 8,700 OE cross-references to help match model-specific needs and support restorations or routine HVAC repairs.
Available Types- Replacement blower motors
- Complete blower assemblies with integrated resistors or speed modules
- Blower housings and impellers for restoration work
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original heater blowers.
OE (Original Equipment) refers to parts matching original specifications for the heater blowers and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM heater blowers engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
A heater blower draws air through the heater core and into the cabin. Motors, impellers and speed-control devices work together with the climate control system to set airflow and temperature distribution. Failures often follow electrical connector corrosion, resistor or module faults, bearing seizure or debris fouling the impeller and housing. Identifying the affected element—motor, resistor/control module or complete assembly—helps plan the correct repair for each Porsche model.
Benefits Include- Restores designed airflow for heating and ventilation
- Ensures rapid demisting and defrosting of windows
- Reduces noise and vibration caused by worn components
- Worn or burnt-out blower motor components such as brushes or commutators
- Debris, dust or leaves accumulating in the impeller or housing
- Seized bearings producing noise, excess load or motor failure
- Corroded electrical connections or failed resistors and speed-control modules
Replacing a worn or faulty blower restores reliable airflow and demisting, reducing the risk of fogged windows and improving climate control response. Correct selection for Porsche models helps avoid secondary electrical strain on wiring and control modules and supports safe visibility and cabin comfort during cold or damp conditions.
Advantages- Compatibility with manual and automatic climate systems on supported Porsche models
- Suitable for routine servicing, HVAC repairs and vehicle restorations
- Manufactured to original-spec dimensions for consistent fit and function where applicable
