When the blower control is set on "HIGH" the blower motor receives full
battery voltage through a high-speed resistor.
A resistor is a device that provides electrical resistance in a circuit. A
device contains different resistors which regulates the amount of current
flowing through it.
This permits the regulation of the blower which have various speed ranges
available. The high-speed resistor is responsible for receiving the voltage
in a blower when the control is set on "HIGH".
