Radiator fan continues even with the car off. I have to unhook the battery for it to go off

sounds like the solid state fan relay has gone bad. This is a fairly common failure for jeeps.

The relay is lacted under the passenger headlight assembly. There are two options to replace it. You can remove the entire front of the vehicle including the bumper, headlights, grill, and headlight support. or you can do it the easy way.

Remove the passenger headlight assembly. there will be one or two bolts that need to be removed and then the headlamp assembly will pop out (sometimes a little force is needed).

in the picture below you can see a series of holes have been drilled. You don't have to get this crazy but you will need to make a big enough opening to get at the two screws and to remove the relay. you can see the relay/connector in the hole to the right and the new relay on the bumper.

Cooling fan keeps running after turning the car off.

You can unplug the fan so it doesnt run the battery dead. Typically what happens with these vehicles is that a failing radiator fan burns out the solid state fan relay, this can also cause the relay to short and supply continuous voltage to the fan assembly. The relay is located below the passenger headlamp but you will need to remove the front bumper to access it.

Where would the relay switches be for the cooling fan

under the hood, driver side (usually) firewall behind battery. (passenger side if battery is there). Look at the back of the relay box cover for diagram. If there is none refer to repair manual for diagram.

Replace the cooling fan relay. It lives under the right headlamp below the plastic bracket that holds the headlamp assembly. You can do this one of two ways. Remove the bumper fascia, headlamps, and bracket that runs across the front of the car. Or, remove the right headlamp and use a hole saw to drill a one and a half to two inch hole in the bottom of the bracket. Once the headlamp is back in place the hole won't show and the integrity of the bracket will remain.

The fan for the cooling system is not working and is brand new

There is a sensor on the radiator that controls a relay to turn the fan on. There is also a fuse in the fuse panel under the hood. Make sure the radiator is full.
