I've been debating about taking the beast to have the AC fixed/diagnosed but I know I'm missing the two lines from the compressor to evap core. I know one line is crown part #56002684 but I'm not sure what part# the other line is... I've checked quadratec/rock auto/4wheel parts/crowns direct site and I can't seem to find the hose that will match up. I found a similar one for the 2.5L but not for the 4.0L. Any one out there have an insight?

At work right now so I can't take a picture of my Jeep, found this one online and marked the line in question with yellow. The larger one to the right of it is #56002684







Thanks!

Actually you have more parts needed than just that hose (part #5600 2731, by the way). But that line that you have outlined does not go to the evaporator to the compressor. It's a liquid line, and goes between the evap core (actually the expansion valve #5600 3173) and the receiver/dryer (#5600 1665). There's an additional liquid line between the condenser and the receiver/dryer (#5600 1656) which is usually mounted on the body, below and just behind the compressor.. The other liquid line (#5600 2732) from the compressor goes to the condensor. There are also various couplers at the condensor and fittings that go on the receiver/dryer, which you also appear to be missing, along with switches and lots of O-rings. And of course, in this day and age, you will require conversion fittings for R-134a, since your setup is for R-12, which is no longer available without connections and a huge bank account. It's also possible that you'll need a different expansion valve that is more suitable to the characteristics of the R-134a.
