Blower resistors are resistors which are used to control the fan speed of automotive blowers. The fan speed can be changed either by switching the blower resistor resistance mechanically, using a rotating lever, or electronically by the air conditioning system.
A hydraulic fan motor directly drives the engine-. cooling fan. Modulated fan speed will depend on. the amount of oil flowing through the fan motor. The oil flow is measured in gallons per (GPM) minute, low oil flow results in low fan speeds.
