Car only has 94,xxx miles an it's a nice car but seems to have this problem. I need help bad. Cars bout to go off a cliff soon.
It's better for you if you start your own thread. You might have similar problems, or problems that seem similar but point to other culprits through diagnosis.
First off, use the electronic odometer trick to see if your fans come on at 116C, which is I know is high, but from what we can tell that is the temp at which the fans come on low speed. High speed is not much further after that at about 118C. The AC turns the fans on high speed. It is possible that the resistor is out on your vehicle, and that keeps the fans from coming on low speed.
