Hello, I'm new to truly working on my own car. My dream car I worked my behind off for, 2007 Mustang GT. She's started overheating. I bought a voltmeter with the light handle. The fuse is fine. I'm not exactly sure if I correctly checked the wires from the fan to the fuse box. But what steps should I take to fix this? How do I know if it's the fan or the relays or whatever it could be with the radiator system?

Crazy storms today, so tomorrow I'll be able to run the car and drive a bit then check to see if the fans come on. I haven't been able to check them after reaching a higher temp to see if vans are on or off. Also, I'm sure the thermostat hasn't been changed yet. Planning on changing it just because it needs to be in the next few days to a week or so, and if that fixes it I'll be a happy camper! Will keep you posted. Thanks boss.
