not sure if you have a European spec model or US spec.
here in the US we have two fans: a viscous belt driven fan, and an electrical fan (which does normally turn on when the AC is on).

The AC fans turns on because the coolant temperature sensor that is located at the bottom of the radiator is unplugged. If it's plugged then check the wiring and make sure it isn't eaten by mice. If the wiring is intact then certainly it's a blow fuse.

Check this video you will find the location of the relays. The fuse box in the engine bay compartment is located close to coolant reservoir.
