WesD Posted July 6, 2019 Share Posted July 6, 2019 There has to be some other provision for the idle control, with the plethora of dealer installed kits, there must be a supplemental harness or wire as described above. The A/C compressor must be triggered to engage somehow, on period GMs the engagement happened through the ECU which also bumped up the idle.

JimBorecky Posted December 9, 2019 Share Posted December 9, 2019 Not sure if this helps some of you parts gurus out there. This page is from an original Parts catalog I found a few years back. There is actually a different part number for "dealer" installed air. 5600 2568 w/Factory Installed Air Cond. 8350 4893 w/Dealer Installed American Air Cond. Once I get further into my build I need to pull the dash to repair it anyway, and plan to replace the heater core at that time, and maybe drop in a evaporator if I can find one that fits. Since I'm doing a LS Swap there is going to be a little bit of creative jeep upgrading in that process anyway. LOL If someone has measurements of the different core and or the empty space they can post that would be awesome!!! Link to comment Share on other sites More sharing options...

drcomanche Posted February 4, 2020 Share Posted February 4, 2020 I'm currently in the thick of it trying to install a system from a 96 XJ on mine. I'd be fine starting a new thread on it where we can discuss all the technical stuff(so we stop beating the proverbial dead horse). From what I've researched, wiring wise, it's not too complex a system to get into and usual just feeds back into itself. If I can manage to pull it off, I'll make a write up for it, but having another thread to bounce ideas around would be beneficial as a technical talk section.

Warren Mohler Posted February 4, 2020 Share Posted February 4, 2020 I am also looking to add A/C, E-bay has a seller based in Texas, aftermarket kit complete about $1400 I called the company and the guy said they have been in business for years and sell a quality kit, I asked about idle control and was told the newer compressors don't pull as much power as older units but idle-up kits were also available if needed. MJ kit was not listed on E-bay site the guy said it was similar to wrangler and all in dash also stated they could put A/C in anything. Has anyone dealt with them? or used their system?

Liketosmash Posted February 7, 2020 Share Posted February 7, 2020 I just installed AC into my 87 Comanche from a donor 88 Cherokee. The Comanche was originally a 2.5 but I swapped the 4.0 from the Cherokee in at the same time. So not sure about what additional brackets or issues you will run into with the 2.5. As for the wiring, some of the wiring was in the Comanche but I had to steal one short harness that went from the airbox to a connector behind the radio/control area. The connector was not the same type but both were I believe 4 pin heavy gauge and the colors matched up so I made it work. One had flat pins where as the other had round. The system has not been evacuated and recharged yet but I see no reason it will not work as everything else matched up. Getting the airbox out and back in was the hardest part.

drcomanche Posted February 8, 2020 Share Posted February 8, 2020 I'm going to start a new thread on the technical info for the swap to eventually become a write up. I have a good bit of the information for it so hopefully it can help those that don't have a direct donor to pull from. Link to comment Share on other sites More sharing options...
RGniady81 Posted February 11, 2020 Share Posted February 11, 2020 For anyone looking to add AC to a 2.5 L truck I have a spare compressor bracket available, also have the underdash box folks will need if converting a non AC truck. I picked up all the parts I could for my swap and have some spare stuff left. Link to comment Share on other sites More sharing options...

Big Dan Posted March 10, 2020 Share Posted March 10, 2020 Since the ebay listing has, essentially, no information on what you get, I would contact them and find out EXACTLY what is included. Link to comment Share on other sites More sharing options...
m2bandit Posted March 12, 2020 Share Posted March 12, 2020 With all new parts it cost me $529. Donor xj for box and wiring cost me $200. Try to get your year... wiring xj changed way too often.

The only thing Jeep left of any use in my non AC MJ was the hole drilled in the relay bracket for the AC relay. If you’re looking at doing this I’d swap the entire wiring from an AC’d XJ ( MJ Evap cores are different). There’s about a foot of AC wires on the engine side of the chassis harness before it terminates, these wires have nothing to connect to on the interior side of the c100/fuse block so it’s pretty worthless.

Duncan Moody Posted August 27, 2022 Share Posted August 27, 2022 Has anyone found a direct replacement evaporator for the dealer installed (1988/89) smaller evaporator? Or one that will fit in the smaller box with newer fittings for a new expansion valve? PO pulled out most of original AC system. Trying to reinstall with all new if possible. Evaporator is the only roadblock at this point. Link to comment Share on other sites More sharing options...
