The blower motor resistor is the component directly responsible for controlling the blower motor fan speed. If a resistor is reading a very low resistance, near 0ω, it's shorted internally. If not then it is a bad resistor. Resistors do not hold a polarity, so it doesn't matter which side gets the red or black lead. The resistor is acting short or open upon testing with a multimeter, or its value is not matching its given value with the provided tolerance.
Additionally, check for visual damage like burns or cracks on the resistor. Antique radio forums • view topic. Web if we take a certain material, say copper for example, and we know that the resistivity is very low and it has high conductance, then we can start playing with the length, width, and height of this piece of copper and we start changing its resistance. How to use a multimeter to test resistors. A resistor might be faulty if the multimeter shows an open circuit or infinite resistance.
