They control the blower motor's electrical current, thereby adjusting the fan speed. RA Rodeo fan speed resistor enable the driver to select from different fan speed settings, ranging from low to high. The fan speed resistor typically consists of a series of resistive co... https://partsfactoryaus.com.au/product/holden-rodeo-fan-speed-resistor/
