Its a tough job. You have to remove the dash panel, including the steering wheel and steering column and then remove the plenum box which involve evacuating the refrigerant system and draining the radiator. Once you get the heater box out, replacing the heater core will take about 10min and then you have to put it all back together and recharge the AC and fill the radiator.
If you are seeing leak problems with the system, you will have to go through this process. If the problem is lack of heat and/or AC control, the problem is more likely the blend door. This is a common fail on the Cherokee. You can get diagnostic information and an inexpensive fix on the HeaterTreater web site.

Make sure coolant level is correct It could be a clogged heater core,maybe it is a birds nest or a rats nest if the car was stored.Usually replace the heater core and it will solve it or maybe it is the radiator itself needing flushed.also it could be the switch is not throwing to the position it should be.If the car was in cold climate before maybe it froze over and then was dooshed with heater core repair stop leak.Thats the best I can guess...
