SBpunk Posted March 26, 2013 Share Posted March 26, 2013 So I found a website http://www.jeepair.com/ac/4-0-liter-inline-6-cylinder-139.php with most of the parts needed and was wondering what its missing to install A/C in my truck. I know I need to get the actual controls for inside the cab but other than that I'm clueless. I'm most likely going to have a shop install it once I gathered everything up since they'll warranty it. Any help would be appreciated. I'll keep reading up see if I can find anything. Thanks Link to comment Share on other sites More sharing options...

dasbulliwagen Posted March 27, 2013 Share Posted March 27, 2013 I didnt read the above article, but I did the conversion in my 2.5. I had to pull the dash and original heater box assy and swap in an HVAC box assy that has the AC evaporator in it, with the AC controls. The HVAC box wiring plugged right into the original dash harness, as i was using 1986 donor parts for my 87. Other years may vary. I then added the compressor and the longer belt needed, added the condensor and lines. Then came the wiring. Some of it was already there, such as the AC compressor clutch wire, but the relays needed to be added. i found out from the 88 FSM posted here on Comancheclub, that the 2.5's had a plug on the driver side wheel well for dealer installed AC, and a wiring schematic for what was needed to get it working. I re created the wiring and it all worked. I also changed the mechanical fan to an electric fan and made it work when the AC was turned on as well. I had to convert the whole thing to run R134a, but that isnt any big deal. One of the best mods Ive done, next to adding power steering. As stated, some of the wiring may be different between engines and model years, but it can be done. Good luck! Link to comment Share on other sites More sharing options...
SBpunk Posted March 27, 2013 Author Share Posted March 27, 2013 Thanks both of you. JeepAir pretty much told me they can't help with any info so Ill be piecing it together with the repair manual and the few sites that have info on it. Link to comment Share on other sites More sharing options...
Biotex Posted March 27, 2013 Share Posted March 27, 2013 I didn't see any high pressure (liquid) lines listed. You have a source, or you going to make them custom? Link to comment Share on other sites More sharing options...

Biotex Posted March 28, 2013 Share Posted March 28, 2013 Rockauto? I didn't see them listed, but I only looked on a couple of sites so far. I'm gathering the parts to add air, and the hoses I have are in bad shape. Link to comment Share on other sites More sharing options...
SBpunk Posted March 28, 2013 Author Share Posted March 28, 2013 If you find a source before me please post it up. The metal lines are going to be the hardest part since there isn't really any junkyards around here Link to comment Share on other sites More sharing options...
