Hello, check for codes. You can take the electrical connector loose from the radiator fan, use jumpers from the battery posts for B+ and ground, use an inline fuse on the jumper. If the fan won't run, I think the fan is faulty. If it does run backtrack to the fan relay, underhood, driverside fender-well area between battery and strut tower. Some things that can effect the fan operation, coolant temp sensor-- pcm-- fan relay-- wiring circuits.
On some systems, when you turn on the ac, the fan runs.
