Most likely a belt slipping!

probably not clutch unless you are missing details
clutch problems will allow the engine rpm to increase with a road speed increase but that is not what you imply
if you did the brakes your self , then take it to an accredited brake shop for a proper diagnosis

I had the same overheating problem in my jeep ! My problem was finaly found out to be the clutch in my fan its a different kind of clutch system it work as this. When your jeep gets warmer the tighter your fan clutch gets .While cool your fan moves slowly. now to test your clutch just warm up your jeep and rev it up a bit if your fan dose not pick up speed then it is sliping.What will come out of this is that you fan will the seez and run full all the time. if you jeep dose not overheat wile moving then it is not your thermo stat period.

try posting why you ask this first
my guess, dash CEL glows, driving,
guess 2, you get it scanned and it shows a DTC error you forgot to tell here, then assume its a bad part, named per above.
why?
first is to get the gas cap tight ( or new)
and then push reset on the scan tool.
then see if the undisclosed, DTC errors, goes away.
this is first. all cars 1996 to NOW.

unless building a EVAP leak down test system is fun. or easy.?? or guessing all parts in the system? why"
see TJ jeep here
posted over 300 times, read the EVAP chapter.
EVAP means in simple terms is GAS tank VENTING and Collection system. its a smog reduction system.
2003 is free to read.

Hesitation is usually a dirty throttle body and idle air control motor.

2004 Jeep... | Answered on Oct 25, 2016


it sounds like you had the same problem I had a while back. There is a couple of "doors" on the blower motor that sometimes get stuck or broken, I took my jeep into an offroad shop and they fixed it with spare parts. They assured me that even if you took it to the dealer it's only like a 15-30$ part but it's the shop time that will kill you.

stock?

TJ jeep that is what it is
and ive posted the answer here 100s of times now.
here goes again
front FOGS
chapter 8L covers this, (8 is wiring, L means lighting)
so ?
see TJ 2003 , same here.
see chapter LAMPS.
then wiring chapter.
schematic is 8W-50 fogs.
wiring + front, (index)


http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

stock car, no hacks?
fuses to cluster, there are 2 fuses.
the cluster has a simple self test mode, try that yet?
first?
2004 TJ,
the book is free

read chapter 8J for self test (IIRC push trip button key on)
if that fails 100% the fuses are blown.
the word is "Actuator test" in that chapter.

now the schematic, in chapter 8w, called wiring
page 40
fuse 26 PDC
and fuse 10 cab JB.

the cluster is really a computer.Display system)

when you jack the scan tool in, some power may leak form scan too to the display.

forget the scan tool, for now,

do the self test. first. if that fails, its lost power.

On a ford all the sensors have a wire that heats them you have upstream sensors up by the engine and downstream sensors located on or before the converter.

Take radiator cap off before you start the vehicle when its cooled off of course then leave cap off watch temp gauge till it reaches normal running temp the fluid should have dropped down in the radiator add coolant itll full you may have to keep adding depending on how much air is in the system put cap back on and turn vehicle off that is how you bleed a cooling system.
