I believe that year had distributorless ignition, instead it uses a form of coil on plug ignition system.
If you open the hood, stand at the front of the vehicle. Look to the left side of the engine, around the bottom of the valve cover (The valve cover is where the oil fill cap is. The oil fill cap is on top of the valve cover), at the bottom of the valve cover on the left side you will see a series of humps. Those series of humps is the coil packs, the coil packs are all in one long piece held down by three or four bolts.
Take out those bolts, gently pry up at the ends of the coil pack and it will eventually come out. You'll see on the bottom side the spark plug boots are attached to the coil pack. After you get the ignition coil pack off, you will see the spark plugs under where the coil pack came from, the boots on the coil pack sit directly on the spark plugs.

the entire air unit under the dash must come out. This requires that you remove the dash board center concle and steering column. Also on some models you must drain the AC system and then requires new Orings from Jeep. Would not do this without experience.

unfortinately the fuse box is under the hood and there is no panel inside the 2000 cherokee or diagram, i had to buy an online manual to find out what fuse went where for my jeep but its not with me. You can just pull the fuses out one at a time and look at them - I know its a pain. It might be your window controll switch - mine is bad as well. It is a common problem for these cherokees especially over 100k, they wear out - I initally thought it was my fuse as well because the lights in the window switch didn't light up anymore - but it is my switch.

Likely you are looking for a 30 amp circuit breaker...(Looks like a small rectangular metal fuse) But...if the power door locks work, i don't think that it's bad (serves locks & windows) My diagrams show a bunch of diodes and resistors inside the master (drivers) door switch, but I've had a few apart and never saw any. (embedded?) Personally I don't see anything that shows me reliability built into the switch...It's a really "iffy" design (one in my niece's Jeep only works when the sun shines on the drivers door) There is also a control module associated with the windows but I've never needed to replace one and the manuals never tell you where they are!
Check power at the switch and check harness where it goes through the rubber boot between the door and body. at least 80% of problems I've seen are either the switch or that wiring. Wires can be spliced and you can get a decent used switch at most scrap yards.
Good luck...glad they aren't stuck down!!!
