BCM issue?

There's a 2004 WJ for sale up the street from me that looks very clean with only about 130k miles on it.

the description says that the signal lights don't come on, AC doesn't come on, and the electric engine fan doesn't kick on. Apparently all these issues started happening at the same time.

My first thought was that the BCM was bad. And that I could replace it and be good, but I don't have time to just jump head first down a rabbit whole of troubleshooting electrical problems.

Are all of those functions controlled by the BCM? Maybe replace thermostat too?

Thanks a lot!
