UPDATE: aright i changed the sensor at the bottom of the fan shroud and the resistor or whatever it was called is burned up pretty bad and rotted out.. so i thought thank god ive solved this... i was wrong.. i put it all back together.. and the fan STILL didnt turn on.. right now i have it hot wired to a switch to keep it cool until i can come up with something else... any other ideas? i think ive just about tried everything...
