Detailed Description
RU-672 is an HVAC blower motor resistor used to regulate blower fan speed in the heating and air conditioning system. For 1984 BMW 318i and 1984 BMW 325e models, this resistor supports the factory multi-speed blower circuit and is specified with a clip-style attachment, rectangular connector shape, and bullet-style terminals. If you are replacing a failed BMW 318i blower resistor or sourcing a 1984 BMW 325e HVAC blower motor resistor, RU-672 provides the correct electrical interface for the listed applications. This part cross-references SKF BR572 for the same application.
Common Issues This Part May Resolve
- Blower fan works on only one speed
- Intermittent cabin airflow from the HVAC system
- No blower operation at selected speed settings
- Incorrect resistor output affecting fan speed control
- Heat or corrosion damage at the resistor connection point
Installation Notes and Tips
Confirm connector style, terminal count, and mounting style before installation. Inspect the blower motor connector, wiring terminals, and surrounding HVAC case for heat damage or corrosion before installing the new resistor. Because no wiring harness or mounting bracket is included, reuse the existing vehicle-side components where applicable and verify a secure clip attachment during installation.
Quality Assurance
Standard Ignition RU-672 is an OE-style replacement part from a recognized aftermarket brand with cataloged interchange support for the listed BMW applications. Cross-reference part numbers include 64111373771 and SKF BR572.
