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.\u003c\/p\u003e\u003ch2\u003eCommon Issues This Part May Resolve\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBlower fan works on only one speed\u003c\/li\u003e\n\u003cli\u003eIntermittent cabin airflow from the HVAC system\u003c\/li\u003e\n\u003cli\u003eNo blower operation at selected speed settings\u003c\/li\u003e\n\u003cli\u003eIncorrect resistor output affecting fan speed control\u003c\/li\u003e\n\u003cli\u003eHeat or corrosion damage at the resistor connection point\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eConfirm 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.
