Heater Blower Motor. Type 2 Bay Window.

The OE MATCH Heater Blower Motor is an original-style replacement component designed to restore the operation of the heating air blower system on the 1976 Porsche 912E and compatible Volkswagen Type 2 Bay Window vehicles.

Fits:

• Porsche 912 E 1976

Diagram Ref No 21

The heater blower is an essential part of the air-cooled vehicle's heating and ventilation arrangement. It helps move air through the heater system, allowing heated air to be directed into the passenger compartment for cabin warmth, windscreen demisting and improved comfort during colder weather.

The Porsche 912E uses a 2.0-litre air-cooled, four-cylinder engine and a heating arrangement that shares important design principles and components with contemporary Volkswagen vehicles.

Unlike modern water-cooled vehicles that commonly use a heater matrix supplied with hot engine coolant, these air-cooled vehicles use heat exchangers associated with the exhaust system to warm the air supplied to the passenger compartment.

The heater blower assists this process by providing additional airflow through the heating system.

When operating correctly, it helps move air through the ducting, heat exchangers and heater channels, improving the availability of warm air to the vehicle's interior.

Over time, the original blower motor can deteriorate because of worn bearings, electrical faults, corrosion, accumulated dirt or damage to the fan assembly.

A failing blower may produce excessive noise, run intermittently, operate slowly or stop working altogether.

These problems can reduce heating airflow, particularly when the engine is idling or the vehicle is travelling at lower speeds.

The OE MATCH replacement heater blower motor provides a practical solution for repairing a defective heating blower without unnecessarily replacing the complete heating system.

Manufactured as an aftermarket replacement corresponding to original reference 261261193B, it is intended to replace the appropriate original blower arrangement on compatible vehicles.

The component is particularly valuable for classic Porsche and Volkswagen owners carrying out heater system repairs, air-cooled vehicle maintenance or restoration work.

Restoring the blower can improve the effectiveness of the existing heating system, provided the heater cables, control flaps, heat exchangers and connecting ducts are also in good condition.

What This Product Does:
The OE MATCH Heater Blower Motor helps distribute air through the vehicle's heating system.

Its main functions include:

• Assists Heating Airflow: Provides additional forced airflow through the heating system.
• Supports Cabin Heating: Helps deliver heated air to the passenger compartment.
• Improves Air Circulation: Assists the movement of air through heater ducts and heat exchangers.
• Supports Windscreen Demisting: Helps provide airflow for clearing condensation from the windscreen.
• Provides Low-Speed Heating Assistance: Helps maintain heating airflow when natural or engine-driven airflow is less effective.
• Maintains Original-Style Operation: Supports the heating arrangement fitted to compatible classic Porsche and Volkswagen vehicles.
• Restores Blower Function: Replaces a seized, noisy or electrically defective heater blower.
• Supports Vehicle Comfort: Helps improve heating performance in cold or damp conditions.

Symptoms Of Wear Or Failure:
Heater blower motors can deteriorate through age, electrical wear and prolonged exposure to vibration, moisture and temperature changes.

Common symptoms of failure include:

• No fan noise when the heater blower is switched on.
• Little or no additional airflow from the heating system.
• Blower motor does not rotate.
• Heating airflow remains weak at idle.
• Reduced warm air delivery.
• Weak airflow through the heating ducts.
• Poor heater performance at low engine speeds.
• Fan operation that sounds slower than normal.
• Grinding.
• Squealing.
• Whining.
• Metallic rattling.
• Excessive buzzing or vibration.

Why Replacement Matters:
A functioning heater blower helps maintain effective cabin heating and windscreen demisting on compatible air-cooled vehicles.

Replacing a faulty motor is important for restoring comfort, ventilation and visibility during colder or damp driving conditions.

• Restores Heating Airflow: Re-establishes forced airflow through the heating system.
• Improves Cabin Comfort: Helps distribute warm air more effectively.
• Supports Windscreen Demisting: Assists the flow of warm air towards the windscreen.
• Reduces Unwanted Noise: Replaces motors with worn bearings or damaged fan components.
• Restores Reliable Electrical Operation: Addresses motor-related intermittent or complete failure.
• Helps Prevent Electrical Damage: Replaces defective motors that may draw excessive current.
• Maintains Original-Style Heating: Preserves the vehicle's existing heating system configuration.
• Suitable for Restoration Projects: Helps return a classic Porsche heater system to working condition.
• Reduces Mechanical Vibration: Replaces excessively worn or damaged rotating blower components.
• OE MATCH Replacement: Provides an aftermarket alternative corresponding to original reference 261261193B.

Inline fuses for Footwell heater blower motors.
Sold as a set of 2, with an easy plug-and-play installation. 

Fits:
Porsche 911 - 1984 to 1986
Porsche 911 Turbo 3.3ltr - 1983 to 1986

Diagram ref no 1

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.

Rear heater blower unit, with steel housing. Fits in the engine bay.
The 91162415103 rear heater blower motor is a direct-fit replacement for the engine-compartment heater fan used on classic 911/930 models. It drives warm air from the heat exchangers forward to the cabin, restoring strong, reliable heating performance. 

Fits:
Porsche 911  2.7L / 3.0L  1974 - 1983

Diagram ref no 1

This later-style unit supersedes the earlier 911 624 151 02 design and is supplied complete with the correct housing/impeller layout for straightforward installation.

Mounted in the engine bay on the left side, it draws air through the heat exchangers and feeds the heater ducts; without a healthy motor, cabin heat output and demist performance drop sharply.

Age and heat can seize bearings, burn brushes, or crack housings—leading to weak/no airflow, noisy operation, or blown fuses. Replace during HVAC refresh or whenever the fan is noisy/inoperative to restore safe demisting and cabin heat.

•  Replaces: Porsche 911.624.151.03 / 911.624.151.02
•  Position: Engine bay – left-hand side
•  Function: Draws warm air from heat exchangers and delivers it into cabin ducts
•  Installation: Direct-fit replacement – no modifications required
•  Common Symptoms of Failure: No cabin heat, fan noise, burnt smell, blown fuse
•  Benefits: Restores cabin heating, correct airflow, and safe demisting performance
