Radiator fan does not turn on with the AC off, the car overheats. Only works with the AC on.

You would have to put it in a pot of boiling water with a temperture gauge or infred gauge, actually infra red gauge will give a pretty accurate reading by just pointing it next to the sensor. You would then check for continuity at the temperature that it is supposed to turn the fan on.
