Check the fuse panel mounted on top of the battery. If it's not obvious, look closely at the contacts and fuses for melting and excessive carbon.
If they are melted/damaged, the complete panel can be purchased at the local dealer and most likely in stock.
If nothing is seen you can start checking power and ground going to the fan with a test light. I have seen the fan(s), fan module, and radiator fan swicth fail. So you might have to dig in deeper.
