But if the resistor burns out or wears out from corrosion, there is nothing to reduce the amount of voltage going to the blower motor for the lowest fan speed, so it will most likely get the ...

The resistor module raises or lowers the current being sent to the blower motor, and the air starts to flow as a soft breeze ...

Adjusting the fan speed sends a signal through a resistor to the blower motor to either pick up the pace or slow it down. The blower motor resistor adjusts the amount of current going to the ...
