Ok, I changed the coolant temp sensor and yahoo, that at least kicks one fan on at what looks like 250, but I think the gauge is wrong. Im going to try a genuine gm temp sender for the gauge and see what happens.
Is the Larger of the 2 fans the primary? If so thats the one thats coming on now and stays on until it cools down some. So the smaller of the two is the one that comes on last at the higher temp? Because I never saw that one come on yet without the AC on.
