Jeep Cherokee Heater Core ReplacementThis is not necessarily a job for the do-it-yourselfer!! It entails removal of the complete dash assembly. You must also evacuate and recharge your air conditioner. With instructions figure on spending the best part of your day!!

aditional info: check the postings here having to do with AC evaporator box issues or wet carpets on the passenger side. They all require the same fix which is total removal of the dash in order to just get to the box. Figure at least a $1000 labor charge alone. If you decide to do it have the styrofoam liner inside the evaporator box replaced as well. This is an excellent example of very poor engineering...in my humble opinion.

Likely your problem is a broken blend door. This can affect the heat or AC, although usually the heater. This problem is easy to diagnose and repair for around $99. Check out the Heater Treater product and website for further info.

Unhook the battery and wait 2 minutes before attempting repair and you will be fine.

Depending on your year of Cherokee, I know the 1991 and newer Cherokees use Champion RC12LYC, Autolite 985, and Denso QJ16HR-U with the 4.0L 6 cylinder engine. On my 2000 Jeep Grand Cherokee Limited with a 4.7L V8, I used Champion Copper Plus RC12MCC4. These are the plugs that the manufacturer calls for. No other plugs should be used. (If you don't believe me, search the internet) Learn how to change the spark plugs on a 4.7L V8 (SEE LINK BELOW).

If the donor Jeep is the exact same year and has the exact same engine and transmission the answer is yes.

Not really a "do it yourself" project. It pretty much requires a complete transmission rebuild and isn't recommended for the shadetree mechanic.
