The air conditioning unit in your car needs to be replaced.

The fans have there own temp control switch. This switch is electrically controlled. Find it and check for bad wires then check power. And ground then unplug the fan that's not working disconnect the battery. Now use the car battery and jump to the wires for the fan your checking to see if the fan motor works. If all checks out you need to replace the temperature control switch for that fan.

Turn on AC with engine running and after a few seconds all fans should start up if working!

depending on the engine temperature the fan is supposed to remain on after you turn the engine off, until the engine reaches a preset cooler temperature. when it reaches cooler temperature usually within 5 minutes or so it should cut off... if you cut it off and it is running 30 minutes later.. then there is a problem with the fan relay or temperature sending unit.

problem is that dealer is just guessing about your problem, it could be anything that might be wrong, the fan is controlled by a relay, and that might have gone bad, try turning on your ac and see if that fan comes on, im not sure but the same relay that works the ac is the same kind that runs the fan, if the fan comes on whaen you run your ac i would look first at the relay, car will get hot if this does not turn on

So the ac is not working. Is the compressor running when you have the control set for ac ?

IT DONT WORK THAT WHY. (on/off)
NO ENGINE STATED, SO on exact answers. 4.0L or 4.7L ???
The engine cooling and HVAC rules govern this (computer tables and logic)
the service manual cover that,
did you SCAN the PCM at the failure then scan it again after, no?
did you know some cars run the fans parked to prevent overheat soak damage to the engine and trans? all have hood sticker warning telling you to stay way from fans, , until fully cooled engine or pull battery neg lug for safety. just saying that so you are safe fiddling all cars.

the fan(s) run via truth tables, logic (computer)
if cold outside why run a fan?, and waste fuel and cause green house gasses for fun. or make noise for fun, answer it doesn't.
it runs the fan ONLY when needed, is the answser
and is very complex, the newer the jeep gets.

On most cars even as old as 1995 , the condensor fan control would stay off if ambient temps are below 50f. this is not new logic.
Chapter 24 covers HVAC. in The service manual SM.
not only that, you failed to test the AC per the SM and failed to scan the PCM to see if there are HVAC faults. causing this fan disablement's. on purpose.
this car come with 2 type HVAC, manual and ATZ (climate control fancy) the rules for each are not the same (potentially)
the PCM controls the radiator fan on the 4.0L with a relay.
so is 100% pure (ATZ/BCM/PCM) logic doing that.
the 4.7L has hydraulic motor powered engine cooling fan
as you many not know the A/C condensor rams hot AIR
to the front of the engine RAD and cause it to overheat
so the engine fan is very much part of this regulation system.
The AC will also shut down for many AC related errors
and will do so if the engine or transmission over heats.
Self preservation.
there are 3 , 4.0L systems, for fan control
clutch fan or electric and one has a PWM modulated fan control module (its a transistor not relay in this case)

her is what chapter 7 states
PWM FAN CONTROL MODULE -
4.0L
DESCRIPTION
The pulse width modulated (PWM) radiator cooling
fan relay is located behind the front bumper fascia
below the right headlamp.
OPERATION
The PWM relay is used to control the speed of the
electric radiator cooling fan. It allows for multiple fan
speeds. This allows for improved fan noise and A/C
performance, better engine cooling, and additional
vehicle power.
PWM relay operation is controlled by the Powertrain
Control Module (PCM). To operate the PWM
relay, the PCM looks at inputs from:
† Engine coolant temperature
† Ambient temperature from the body controller
† Vehicle speed
† Transmission oil temperature
† A/C switch position (A/C request)

the SM does not list all rule and tests for this device.

more..?
here more quotes from your missing book
If an open or shorted condition has developed in
the relay circuit controlling the electric radiator fan
or fan control solenoid circuit controling the hydraulic
fan, a Diagnostic Trouble Code (DTC) can be set.
If the problem is sensed in a monitored circuit
often enough to indicated an actual problem, a DTC
is stored. The DTC will be stored in the PCM memory
for eventual display to the service technician.

the 4.7 liter engine the fan speed is base on above
and says, A/C system pressures.
the 4.7 then can can run at 500 rpm even when OFF. (SM)

now how to test the fan.
get engine hot, (drive 10miles say)
then park, and lest engine idle until the engine overheats
it will (but not in alaska, dig?)
and then the fans come on at bout 225f .. (about this is ball park)
electric fans
if using a 4.7L say so, its totally DIFFERENT

The blower control module needs to be replaced. This will fix a ac, heater fan that runs all the time.
