i just noticed a week ago that my fans continuously run on high. it just started doing this. they dont come on until the water temp reaches around the 210 mark. so far i have changed the thermostat, water pump, temperature sensor, two of the three fan relays and it still does it. I thought it may be the high pressure switch on the airconditioner but temperature seems to be the only thing that affects it. Can someone point me in the right direction?
