Default 02 is 300 cooling fans doesnt come on!!!

i jhave a 02 is300 5speed, cooling fans will only come on when the Ac is on. when not on the temp gauge goes up, it hasnt over heated but i notice that the fans wont kick on. but only when the AC is running. any idea?

i believe the cooling system runs off a seperate relay to trigger the fan. maybe check the fuses and switch some relays around to get it to work. but first make sure the thermostat is working fine
