Under passenger head light,must remove, relay is visible
The 1997 Jeep Cherokee fog light relay fuse can be found in the fuse box. The fuse box is located in the engine compartment. The location of the fuse can be found on the inside cover of the fuse box.
Below the passenger side head light assembly.

Where is the windshield wiper relay located on a 1996 grand jeep Cherokee
Behind the glove box. It was an option and might not be there unless it was an installed option.
Use a test light connected to the fan motor - if it lights fan motor is bad if it does not light could be fuse, relay, switch, or resistor
Swap the relay with another like relay.
It is a 4.8 amp 12 volt circuit breaker for the windshield wipers
