I have a 1988 MJ that according to VIN began life as a 2.5L. It's been swapped with a 1995 4.0L from an XJ. I need help finding the correct Air Conditioning kit to put into this vehicle. Any ideas?

I'm looking to buy a doner 97 xj to do the face lift on my 89 comanche. The factory ac has gone out, does anyone know if the ac system will just swap over from the xj? Then I don't have to worry about troubleshooting and retrofitting the old r12 system.

So I recently bought an 88 2.5L from a guy that had put a lot of effort but no money into keeping it running. Cheap aftermarket guage cluster when sensors would fail. Push button light cause the dash lights would cut out every no and again, local bike cable release cause the hood cable broke. Fiberglass and chip board cause the floor rusted through. All that aside it started and ran alright best I could tell. Replaced the ignition system(starter relay, coil, cap, rotor, plugs, wires) Drove it for about 1000 miles then went after some other repairs. Traded the ax5 from my 89 that is a parts truck now for the ax4 that was in it. Replaced some faulty wires, Seemed like it was running well, well enough. Charged up the AC (which he wired a direct switch to the compressor for cause I guess the climate control failed.) Drove it home from my buddies where we were working on it. I was sleep deprived and loosing it on my hour drive home, made it home safe, but only just barely. I recall that it began to run rough toward the end of my journey but not much more than that. I leave it for a couple of days as I had things that necessitated my GFs car instead of my own. I finally have time to look at it. I jump it because I left the compressor engauged and drained the battery, and my buddy yells at me that its shooting oil everywhere, the sending line from the aftermarket oil pressure gauge had been melted through and was shooting a perfect jet of oil up and into my hood which was deflecting it in every direction. This is my best deduction. The AC line burst (evidence of this is present) spewing Freeon and compressor oil all over my engine bay. It contained(or rather is) a solvent that spent the weekend eating through all kinds of plastics and rubbers in my engine bay including: The oil pressure line The black plastic cable path that contain every engine wire the boots to my brand new spark plug wires stripped the paint from my firewall and hood and left corrosion/aluminum salt built up on: alternator ac clutch bell for the fan water pump starter relay coil pack fusible link wires!?! What should I do? This truck was supposed to be a minimal amount of work while I cut the front off of my 89 rust bucket to fix the 90 4.0 that I t-boned a lady in. I have a 1hr 50 mile commute Cash is tight now but I am also trying to improve this as I go. The 4.0 is supposed to be my daily driver and I would like to have the 2.5 as a second little runner truck for employees incase they need to take some equipment across town, but having employees is a year away.

Ok, I managed to get my hands on some suitable replacement for the vacuum line in the first picture. It connects in the engine bay to the vacuum solenoid in the second picture. Where the heck does it go in the cab? I've got the dash apart, I had assumed (incorrectly) that it attached to the A/C controls but can't find the other end of that sucker anywhere. Any ideas?

Hey everyone, I recently acquired a nice little cache of R12 and was wondering what the going rate was for them. Thinking of selling a few off to finance an upgrade on my truck :yes: Never had any to sell before so just wondering how much to post them up for. Thanks!

Hello everyone, I have a 1988 Jeep Comanche Eliminator, 2wd, 4.0 aw4 trans with about 86,000 miles on it. My truck will start every time and idle great at 800 /750 rpm when its cold but it fluctuates a little bit. With the AC turned off and the truck is at operating temperature the truck will idle at 500 rpm or lower at times and fluctuates a lot more. The truck drives completely normal until you come up to a stop light and the idle drops and acts like its going to stall but goes right back up to 500 rpm. When the idle is at 500 rpm It hesitates very little right when you take off but other than that it drives fine. The truck will not stall at all but it feels like it going to but it doesn't. This is when I am very curious. With the AC turned on and the truck is at operating temperature the truck will idle perfect at 750 rpm and will only occasionally fluctuate. I am just wondering what could cause the idle to be fine with the AC on and the idle to be low when the AC is off. Note: This low idle has just started happening right after I changed the fuel pump other than that it idle fine before the new pump. the idle has always fluctuated when I first got the truck but hasn't been a problem. What I have Changed so far: New Plugs/ wires New distributor cap/ rotor New coil IAC TPS CPS MAP censor New vacuum harness New fuel pump/ filter Any help will be great. Thanks.

My 87 Comanches AC compressor won't kick in. I hooked the compressor up to straight 12 volts and it kicks in. I replaced the relay but I'm still not getting 12 volts to the compressor. Can anyone help me... I've see on other forms that it could be a thermostat switch. What does that look like and where is it located. Any other ideas??? Thanks Jim.

I know somewhere on this forum it the info i need and have tried to find it without any luck. We too dads MJ up to the shop to get the ac running again.. Saturday we drove about an hour with the ac on after it rained and water started coming from the dash, The MJ has not leaked prior to refilling the ac so i dout its rain water leaking in. but i remember heading here that there was a little hose that allows the condensation from the ac through the firewall and to outside.. I just can't locate that tube to clean it...
