Thanks.
The individual resistors in the pack are used only to provide lower blower motor operating voltages for the lower fan speeds.
In the HIGH speed position, no resistors are used, it's just a straight-through electrical connection (via the resistor pack module and switch)from the blower to switched battery power.
