There is no such thing as a fan switch on your car.
Your fans are controlled by the engine ECU.
There is a temperature sensor which the ecu uses for various jobs which is fitted to the metal water rail which runs under your inlet manifold.
If you look down and behind your alternator you will see a grey sensor which has 3 wires going to it, this is the sensor used by the ecu.
