Thermostat. ..

Hello everyone I have a question my radiator fan stopped working on me I had a computer hooked up to my 04 bmw x5 4.8is 4.8is and it said the thermostat is bad. Would that have any reason why the fan isn't working ? I'm not good with this kind of stuff that's why I come to you . If you have any opions or anything else I should check please let me know .
Thanks
Brandon

I think there's a sensor by the thermostat.

It is the big fan between the radiator and the engine. If you open the hood get somebody start the engine while watching and listening have that person turn on the AC. You should be able to hear fan start running. Think thermostat doesn't come in to play with AC. You need to check the fuse to start with. Good luck

You can unplug the fan , then run direct 12v power to check if it's working .
