I have the black grille and headlamp doors to go for this setup, but they are very faded. Should I just paint them with regular matte black paint or is there a better color for the oem look?

Ah ok

The little ball inside my 89 Base model MJ has 2 connections for the vacuum lines. The pill shaped reservoir from the 87 MJ with Cruise control has 2 connections on each end. What are the two extra connections for? A diagram would be great too. I assume it has to do with the cruise control I just don’t know how it goes

Yea I feel like an idiot. Both the 88 and 89 XJ at the junkyard had the sensor screw right into the radiator, rather than the hose setup like in the diagram. It wasn’t til then that I remembered I had an OEM 87 MJ radiator at home, so I’ll be using that

alright

any 88 XJ should have it right?

This is a continuation from the r12 to r134a thread. For those who don't know, 14 is the plug for your electric fan. You may be in the same situation as me if you or a PO swapped your oem driver side radiator hose for a later model hose, leaving nowhere for the electric fan sensor to go. Does anyone know if/where you can just buy the parts new(talking about 19, 10, 20, 15, and 18)? I'd rather just do that so I have new hoses but if not I might already know of an XJ that has them.

I'm gonna make a new thread about this incase anyone else has the same issue.

sweet!

Does anyone know if you could buy these parts new anywhere?

Yep that looks like it. I might go back to that 88 2 door and get the hose setup.

I have a fan shroud it just wasn't in since I had the front end apart. But that makes sense I think the radiator is the issue. My radiator was ordered from rock auto for a 96 XJ, then swapped into my truck. I'll get a pic tmr but earlier today I saw what I think is that plug laying by the airbox.

While doing my a/c charge I forgot I had no shroud so for a moment my temp got in the red and the fan still didn't kick on. May just be bad tbh, I'll test it out tmr

As in the one on the back of the head that tells the gauge what to do?

Ok hopefully this is the last update to this thread. Turns out I had wayyyy overtightened the hose on the bottom of the condenser and had pulled the threads. So that same day I rushed to the junkyard and luckily found an 88 2door XJ which had it's entire A/C system recently replaced. Using the condenser and each line from it, I did a vacuum leak downtest overnight with it and it held. Fast forward to today and all the R134A is in and it's blowing cold! Pressures were normal. Only thing I need to adress now is why my electric fan never kicks on. It's from a 96 XJ, but the connector was the same so I had it plugged in. I'd really rather not just wire the fan up to a switch on the dash, so if anyone could point me in the right direction as to what tells the fan when to turn on, thank you.

I might too. Not very happy with how this rock auto hose fit. The "muffler" on the one is no where near where it should be, and theres two slight kinks in the rubber line, but we will see how it does under vacuum and pressure.

Yea thats what I did. Everything is now finger tight. Was going to try to get all the fittings fully tightened down tn but I started to kink the 90 degree fitting on the bottom of the receiver so decided to stop and come back tomorrow when it's not dark out and I aint rushing. So assuming all goes well, I should be able to start doing a leakdown and pressure test with the whole system tmr, and if it seems healthy then I'm charging it

Now that I'm looking at rock auto more thoroughly, none of the driers have a HPCO, and these are designed for r134a, even tho they are under the 1989 MJ section. Would a factory r134a system not have a HPCO? Do I need one in mine? How important is it?

new drier doesn’t have the switch. Can I just throw the old one on there or do I need to order a r134a switch or do I even need one at all? Kinda bummed bc I was ready to put in all my new a/c stuff

You can submit a request to be in the central parking area where your jeep will get more attention. I got accepted. Its just that you have to be there by 8:15 and aren't supposed to leave til 12

Saw a mint pioneer towing a trailer in Monticello, Ga today.

Yea I figured those were a whole different breed

Yea feel free to point out things I forgot about or simply never knew about.

This isn’t the most in depth or important but since I have the two I figured I’d make this post and possibly save someone from grabbing a part that one fit from the junkyard. If you didn’t know, the number of pieces and way it’s split between the headlamp doors and grille changes in 91(also note the Jeep emblem changes style). The newer style only consists of 3 pieces. If you take a 91+ header panel and try to install older headlamp and side marker doors, they won’t fit. However, if you do some trimming like I did, they can slide into place, although the way I did it was very crude and everything was barely held together. The blue lines in the pics show where I cut, and the circles show where I may have trimmed some, but can’t really remember. As far as I’m aware overall dimensions will line up with the fenders, so if you wanted to swap a different style onto your MJ or XJ, you can, just as long as the grille and headlamp doors are the same style, unless your willing to modify the panel. The red one which is spray painted white is off a 96 XJ. The regular red one is off an 87 MJ

I still haven't installed the new cruise control motor and vacuum lines and such yet, so that may end up fixing it when I install it. After I install the rest of my CC, if I still have issues then I'll look further into it.
