1996 Heater AC Unit Box

Year: 1996
Make: Jeep
Model: GC
Engine Size: 4.0
Refrigerant Type: R134
Country of Origin: United States

I need to replace the evaporator in my Jeep GC and was thinking about picking up a heater AC box and rebuilding it to have it ready to install when I pull mine out on the Jeep. The one I'm looking at is in a 5.2 and 4 wheel drive. Would these two packages interchange or are they different. Just trying to cut the down time.

I wouldn't go to the trouble of doing that. Remove the original unit, replace the part, reassemble and then reinstall.

I had the chance to check both a 93 with a V8 and a 96 with the 4.0 engine. Under the hood, it appears the lines going into and out of the evap are the same at the firewall. Didn't check heater hoses though. The interiors seem to be the same, the evap drains are the same, but I can't be sure about the configuration of the box itself. I didn't pull the dashboards.. Now is the time to see how helpful your dealer is.. If he can look up the part numbers for each, that will tell you if the boxes are the same or not. There could also be a difference with manual and ATC controls, as far as the blend doors go..
As Tony stated, you might be better off, if you're not sure, to just switch the evaps once you get your box out. That is the hard part, not switching the evaps.. Just my observations from "outward" comparisons, hope it helps..

BTW...It wouldn't hurt to take the other one out if you have the time, just for practice before you remove your own.. Lot of work, and better to break parts on the other one than your own...

I wouldnt change the box!!! that seems to be one of the easier evaps to change!! when removing the box I do NOT remove the dash completely I drop the steering colum take everything loose that needs to be and then take the dash back on the passenger side and tie it up with a ratchet strap from the roof rack (look there are holes in the front on the passenger side of the roof rack) also take fender covers or towels and cover the console as to not scratch (I tape a red rag around the colum) it gives you plenty of room to get to the box out and be careful not to scratch the door panel when you are removing the box!

I had to remove the IP from an S-10 to remove the heat core box, the first thing I quickly learned is that my body doesn't bend that way, so removed the front seats first and threw down an old sleeping bag, may as well be comfortable.

Second thing I learned is there are zillions of cables, mostly on the drivers side, I was on the riders side, so after removing the screws, tied the dash with a short rope to the visor bracket so I could swing it out. I just removed the cables that prevented me from getting enough clearance to swing it out. Suggest you use masking tape and a magic marker using a 1-1, 2-2... sequence for putting it back together again, I had to remember the 17-17 number, the last one so I did get all seventeen back together again. After installing the new heater core and box, #17 that was the longest cable went back first working backwards as each cable was shorter requiring that the dash be moved closer to the front.

Laying on the sleeping bag with my feet up on the rear seat, also a good time to take a nap, may work for you.
