Sounds like the fan controller module is dead. One of our Jeeps has done the same thing. As a fast fix, we rigged the fan to be on when the lights are on. This fix may also work for you as well, but it is a temporary fix.

There are usually at least 2 temp sensors. One talks to the fan relay to run the fan when needed. The other one talks to the computer. Is it possible you changed the computer input sensor? They usually look similar. I have a V8 so am not able to describe the location of the probable guilty part on your 4.0 and I'm 5000 miles from my service manual.
 
With electical power on, grounding the electrical connection to the correct sensor should fire up the fan. If I'm wrong about this one, someboby please chime in.

1999 JGC just going to heck by cafetom

Hey there,
 
I have a friend who JUST paid off his 99 JGC and EVERYTHING is going on it. It seems like a money pit and I told him that. I'd like to hear from others.
 
He has a rear wheel seal and bearing that is going out. It is leaking all over the place. He also had the Pitman gear box that goes through a pint of fluid every 20 miles. Warped brake rotors, and a slew of other little problems that are going to add up.
 
He can not afford another vehicle, nor can he afford the repairs. I think he should sell it and get what he can for it and get something else. What do you all think.

Hey i had the same problem with my jeep. I have an 2000 Grand Cherokee I-6
I was having the same problems the fan would stay on( but i just re-started it and it turned off) and the lights would dim, it would over heat in slow driving or when stopped, and it would hesitate turning on. turns out my fan motor had died and the car was trying to cool its self and the battery and alternator were fine i just over worked them. I had to replace the entire fan assembly and a new battery it cost a pretty penny and took sometime but it worked. There was a recall on my fan assembly that was checked out by a dealership in Florida and they said everything was fine back then and sense they checked it out my local Jeep dealership said there was nothing they could do. but good luck! Jeeps are awesome the mechanic said that he was surprised that it went so long (5 weeks )

I haven't had a chance to work on the problem yet due to my work schedule and the weather.
I do have another question though, the starter runs but the engine doesn't engage.
I tried hitting on the starter with a mallet to see if it might be locked up but that proved useless.
I guess I'm questioning the bad starter because I didn't think that if it just stalled when I turned a corner that a bad starter could cause it to stall? Can a bad starter cause problems when the vehichle is already running?
Needless to say I'm not a mechanic so if my question seems dumb I apologize!
Thanks again.

Wow. Sounds like you may be into more than one glitch or some truly serious electric gremlin. I fear the days of bashing the starter are kinda' over, although I'd have done it too just 'cause I have a big hammer and I'm old.
 
As to why it quit? No guess. As to the starter situation, I'd say a remann'ed starter assembly is just about a must.

Does the starter engage or do you have zero/nothing?
 
My 97 would kill and I would have zero power; no radio, starter, lights, etc. If I moved the tilt wheel up and down, the power would come back on. The issue was a short in the ignition wiring. I pulled the cover off the steering column, repaired the contacts and made sure there were no bare wires. That was 20k miles ago and no problems since.
