The blower resistor in a BMW 525 is located under the glove compartment on the front passenger side. Function of the blower: The automotive blower's function is to direct the cold air from the air conditioning evaporator or the hot air from the heater core into the vehicle cabin. Composition of the blower: It mainly consists of the following six components: motor, air filter, blower body, air chamber, base (also serving as an oil tank), and oil drip nozzle. Working principle: The blower operates via an eccentrically mounted rotor inside the cylinder, which changes the volume between the vanes in the rotor slots to suck in, compress, and expel air. During operation, the pressure difference in the blower automatically delivers lubrication to the oil drip nozzle, which drips into the cylinder to reduce friction and noise while preventing gas backflow in the cylinder.
