Answer 3

this is from experience... you have to remove the whole dash to get to the heater core under the glove box, it took me 2 days. I would take it to the shop and let them have the headache. I guarantee that will be money well spent

Answer 4

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.
