Yes, there is not an access hole that allows any other method. Start by disconnecting heater hoses, then remove dashboard ***'y. Not too bad on Jeeps. Then you may or may not have to remove the whole HVAC box depending on where the lid for the heater core cavity sits. Usually this whole box must come out to get heater tubes thru the firewall. Then you can take the cover plate off, unbolt the tiny screws that hold down the arms, and remove the offending core. Good luck, takes me a day or less, and I've done it for years. Worth the 400-600 plus that shops charge for this if you are not into meticulous work, tiny screws, and lots of crawling around inside a Jeep. Don't worry, you're not alone in this. Only a handful of today's cars can be re-cored without removing the dash, or at least setting it back on the seat (on a blanket) to gain access to the HVAC box. Hope this helps you make your decision. TT

Bound to be online, somewhere. Google "jeep fuse box diagram". I found a 96 grand cherokee diagram in just a moment's search. Many, many pages there. Also jeep forums, 4wd.com; libraries are an excellent source also, if you can find the right repair manual. Good luck.

Where is the heater core located in 1997 pontiac grand prix


Core is dead center in front of the shift console. There is a bunch of plastic that needs to be removed to get to it, including (on most) the console.
Hardest part of job is getting to the heater hose ends on the firewall (difficult to get to from above or underneath unless it's on a lift, but not impossible) Haynes and Chilton have pretty good instructions for that job and you can use the manuals for other stuff as well...(about $20)
Job takes some time but is much easier than a Jeep!!!! (all day job)
Good luck

How do replace a 2000 Jeep Grand Cherokee evaporator? Do I need to take the whole dash apart?


I have read it is quite a job. The heater core in my 97 Grand Cherokee (which is in the same location as the evaporator) is leaking. I think you have to remove the entire dash to get to it.

Heater core 2002 jeep grand cher.


I purchased a Blen Door repair kit. for my 2002 Jeep Grand Cherokee after having only cold air blow out of the passenger side for over a year. I found it on EBay. It requires you remove the glove box, cut open the heater box and replace the blend door. I really didn't want to cut that open, however, with the tape that comes with it, I have had no problems with it leaking any air. The dual control no longer works, the temperature is now completely controlled by the drivers side, but to save $1200, I was willing to do this. I have taken the entire thing out before to replace the heater core, didn't want to do it again.
