Turn the ignition key to the On (not start) position then On/Off three times in succession within 5 seconds, "On" (On/Off, On/Off, On/Off, On). At the fourth "On" the odometer will be replaced with codes. If no codes are present then "Done" will appear.
There are two ways that the codes can be displayed. The first is by the check engine light flashing like morse code. However I am pretty sure that starting in 2002 the codes will be displayed in the digital odometer, such as P0101 or P0302.
If for some reason you are unable to get a read out of the fault code you can try places like Auto Zone. They will read your codes with a scanner for free.
Just be prepared to write down the codes as they appear in the display. For a description of your codes either repost back here with a list of them or follow the link I provided below.
I hope this helps but if not please let me know and I'll try and work through it with you.
Good luck and happy holidays to you and yours.

My 98 Jeep Grand Cherokee had the same problem. Over heated when standing still. Took it to dealer and they could not find any problem with cooling fan. After doing my own investigation I found out that the electric cooling fan would begin to seize up after about 1hr. of operating. (gets hot)
The dealer would look at fan and see that it was running and think its ok. The problem is, it wasn't running fast enough.
I have a relay on the right side of front fender and jumped the fan to stay on with motor off. (must know what your doing). After about 1hr. fan started slowing way down. Returned it to dealer told them what the problem was. They were not smart enough to jump the relay so they put a couple hundred miles on it even though i told them it works OK when moving. Make sure you tell dealer to use the relay to jump.
Replace cooling fan motor. Works great
SOURCE: i need to drain my radiator on a 2002 jeep grand cherokee
On many of these, the drain is on the right front of the radiator, sometimes requiring removal of a small panel in the grille or the entire grille. The ones I've serviced, after geting to the drain I've found that it dosen't turn. It is far easier to ignore the drain altogether and remove the lower hose at the radiator. Don't do this on a hot engine unless you like hot antifreeze baths! (I don't)
Good luck
