Maybe somebody found this before but here is what i discovered to be a free fanswitch mode:
As we know, on FD when you turn AC on, fans come online too, but racing a car with AC on is stupid, because you are wasting loads of power. So i poped the hood and pulled out air cond fuse from fuse box, located next to diagnostic box. now, when i push AC button, AC does not start, car doesnt lose power but, fans still kick in. This mod is only applicable for racing purposes because you realy dont want to drive a car withought AC in summer heat.
