SOURCE: Heater not working
Depending on what package the Jeep came with, you could have a broken or disconnected vacuum line to the heater doors.
If it's electronic, there could be a blend door accuator not working.
There could be a bad heater control valve or just a engine thermostat that's staying open all the time.

SOURCE: how to remove heater core
Is a typical case, but we can use like a general method:
First remove all the water from your system by draining the radiator, it's best to do it this way so you can add new coolant and keep the mess to a minimum, after your water is drained, go ahead and remove the heater core feed lines.
For the specific case, Grand Cherokee, check this info, maybe the answer are in there: ZJ Secc 24 Heating and Air Conditioning (Page 41 and Next)

I suggest review the ZJSecc24-Heating-and-Air-Conditioning
First you'll need remove the heater A/C unit from the vehicle; after, remove the heater core retaining screws, and finally, pull the heatrer core straight out of the housing.
Hop helped with this (remember rated this help) Good luck.

Since your blower is working and it is a heat issue,thats where we'll
start,First thing is have you checked the coolant level in the radiator when
engine is cold,make sure it is filled to top,next verify you have coolant in
reserve ,Start your van and get it up to normal operation temperature,If your
heat gauge on the dash works correctly it should be 190 degrees,Now lift the
hood and locate the two heater hoses going into the heater assembly at the fire
wall,Both hoses should be hot to hold on to,if both are hot and no heat inside
your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

Tips for a great answer:
it's clogged it can be cleared with the use of Garden hose pump. The water has
to be turn into the heater hose line and then water has to be removed
out via the pump.
