Air conditioner series resistor. Porsche 928 1989-93 - 92861610100
Porsche
92861610100
Product Information
This is a genuine Porsche series resistor (part number 928 616 101 00) designed for the HVAC/blower motor circuit in the Porsche 928 series. It’s an essential replacement part used in the heating, ventilation and air-conditioning system.
Fits:
Porsche 928 1989 - 1993
Diagram ref no 37
Part Numbers / References: OE references 928-616-101-00 or superseded 928-618-101-01
What it’s used for:
• It regulates the blower motor speed in the vehicle’s climate control system, allowing your car’s heater or air-conditioning fan to run at the correct speeds (low, medium, high).
• In the classic Porsche 928, this resistor ensures the blower motor receives the correct electrical resistance so that fan speeds are stable and predictable rather than erratic. 928sRus, Inc.
• When this resistor fails, you may experience blower fan only working on one speed (often high), or not working at all - making it impossible to properly control cabin climate.
Why it needs replacing:
• With age, repeated heat cycling and electrical load cause wear on this resistor unit. It can overheat, degrade, or fail, causing loss of fan speed control.
• A faulty resistor can lead to reduced functionality of your HVAC system: blower motor stuck on one speed, no fan at all, or intermittent operation.
• Replacing it with a genuine OEM part restores correct operation, maintains authenticity and reliability of your Porsche.
When to replace it:
• Whenever your blower motor isn’t working correctly - e.g., only high speed works, or no speed control at all.
• During routine HVAC system service or restoration of a classic Porsche 928, especially as these original components age.
• If the resistor shows signs of corrosion, overheating damage or the fan control switch has been replaced without improved function.
