Overview

The BMW Genuine Parts 64116934390 is a blower regulator designed for the E65 and E66 chassis BMW 7 Series vehicles. This component is part of the HVAC system and regulates the fan speed of the blower motor.

A faulty blower motor resistor, also known as a blower regulator, final stage resistor (FSR), or final stage unit (FSU), is a common cause of blower fan problems in these vehicles. Symptoms of a failed FSU can include the fan not working at all, only working on one speed, or cycling through speeds erratically. In some cases, a failed FSU may also cause battery drain.

The BMW Genuine Parts 64116934390 is a blower regulator, also referred to as a final stage resistor (FSR) or final stage unit (FSU), crucial for regulating the fan speed within your BMW's HVAC system. While FSU failures are often attributed to age and heat, it's recommended to inspect the wiring harness plug for signs of overheating and consider replacing the microfilter and checking the blower motor's operation, as a failing blower motor can contribute to premature FSU failure. This specific part is manufactured by ACM and is a direct replacement for BMW part number 64116934390. It is compatible with various BMW 7 Series models from 2002 to 2008, including the 745i, 745Li, 750i, 750Li, 760i, 760Li, and Alpina B7. Ensure proper fitment by checking the detailed compatibility list for your specific year, model, engine, and trim. When replacing the FSU, it is advisable to also change the microfilter and inspect the blower motor's operation.
