Various components are involved in the A/C's operation, but the actual dissipation of heat from your car cabin happens in the condenser, a radiator-like device through which warm air passes for cooling. And, that cooling is provided by the condenser fan.

The condenser fan is nothing special. Its job is to dissipate the heat in the refrigerant coming from your car A/C compressor, reducing the heat for another cycle of heat collection in your car cabin. Just like any other fan, it's made up of a motor and several blades.

The motor is the component that operates the fan through the power coming from the battery, while the blades are the actual parts that spin to push or pull in air through the coils of the condenser. The blades are made either from aluminum or steel, and they come in several numbers (from six to eight).
