Quiet cool whole house fan parts. Most commonly the fan will only run on the highest setting. A blower fan is connected to the negative battery terminal also called ground on one end and to the positive battery terminal through a blower motor resistor on the other end. In other designs the failure of 1 resistor means you lose only one speed.
