Why does the radiator fan turn on when the AC is on?
The radiator fan and AC have nothing to do with each other. The radiator fan is on a thermal control and turns on when the temperature reaches a set point, it has nothing to do with the AC at all. If your car is at running temperature and the AC fan is not coming on (assuming it is not -20 degrees outside) then there are likely one of a few causes.
How can I tell if my cooling fan is working?
The quickest way to tell whether or not the electric fan (s) are working is to start the engine; let it reach normal operating temperature and then turn the A/C on. The cooling fan in the engine compartment should turn on to pull air through the radiator and A/C condenser. A main cooling fan for the radiator.
Where does the cooling fan in the engine go?
The cooling fan in the engine compartment should turn on to pull air through the radiator and A/C condenser. A main cooling fan for the radiator. A second fan for the condenser.
When does the AC fan turn on in the winter?
The fan only turns on when cooling or heating (in winter) is required. If you can tolerate most of the summer heat – save for the absolute hottest of days – you’ll want to use the AUTO setting. The AC fan kicks in when needed and stops running when the job is done.

Can a car fan be used while the AC is off?
In fact, such conditions prevail except in very hot weather, so you almost never see your cooling fan working while the AC is off and the car is moving. By contrast, heat transfer through the AC system is near-constant under given weather conditions and is in most cases demanding enough to justify active cooling by a fan.
Why does a small car have a cooling fan?
That depends on the car. Small cars typically have stacked AC and engine radiators cooled by a single fan. In that case, it makes sense to keep the fan on while the AC is running because the AC thermostat operates by manipulating compressor clutch, rather than the fan.
