Did you check all fuses? yet? in both boxes?
first off the schematic (516pages) is here.
http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service
so you look any time and see why.
ill direct you to the pages.
the radio too can be complex. ext. amps. ill assume its 100 % DEAD
ill do radio dont play in run pos. of ign. sw., (easier)
there are 3 Cherokees, gas, desiel and export. so> and ENGINE! size
so every page is repeated 3 time. you sort that
6 fuses involved here, just for the freaking radio
but fuse 17 is the key fuse. see that. and the marking
RUN-ACC A31 , in JB (bad A31 power feed is the prob)
fuse 17 marked, X12-16rd/wt
fuse 18 kills windows. and is A31 feed too.. hummmmm
are both fuses blown, might check that..?????
so we look now at A31 (fuse 17 and 18 measure 0ohms with meter)
A31 goes to the Ignition switch, USA RHD GAS car, is most
complex and the first section of the switch has a pin3 to pin4
jumper. this jumper allows A31 power feed to reach the things
you find are dead. see page 8w-10-15 or pdf 35
see pdf page 240 for radio wires.
so what is wrong, i dont know,
but my voltmeter will tell min in 1min flat
got 12v on the A32 feed?
yes, then F17 -18 blown.
if not the jumper is bad in the ign. switch

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!!!

I cannot give you an answer without verify that this is your vehicle, and that you are the owner.

Which fuse box diagram are you looking for? There are two fuse boxes in your Jeep. The diagrams will not tell you anything that the diagram in the lid of the fuse box will not tell you. What are you trying to fix? If you are have some type of electrical problem, you are not likely to fix the problem by replacing the fuse.
