Let's talk about air conditioning!

Well Tony did buy the assorted pack of the proper green o-rings. I installed them with refrigerant oil on them for lubrication during the install. Tony I would get a can of dye and recharge the system and see if you can locate the leak. We did use a used a/c compressor and a used evap. So don't be to quick to rip the dash out again . Also a weak compressor can also cause it not to cool properly. When I charged the system the pressures were right via superheat.

X2 Find the leak first

"The absolute best thing to do for AC O rings is to pull them, walk down the the best auto parts store you can find and set them on the counter and have them get their O ring box out and match them. That way you get what you need every time. I have done that several times and never thought about getting a kit."

I’ve got the same box of o-rings they have, and have never had a problem with them leaking on any other vehicle except for the xj.
After changing them several times I got an o-ring kit for the xj, no more problem.
