Information
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

Information
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.
