Hello Everyone,
This is my first time posting here in this forum, so I hope I am in the right place. I recently purchased my first Jeep, it is a 2004 Jeep Wrangler Sahara with 124,000 M. The exterior is in great condition and the interior looks good. There are a few issues with this Jeep and I wanted to see if I can get some help on how to resolve them.
The first major issue is an oil leak, I suspect that I may need to replace the oil pan gasket or rear main seal. I would like to know how to replace the oil pan gasket and rear main seal safely. If you have done this before on a Jeep Wrangler I would really like to know how it went for you. I replaced gaskets before on other vehicles but never on a Jeep.
The second issue is that I think that the AC is dead, when I turned on the AC I do not get any cold air coming out from the vents. I would like to know some trouble shooting techniques to make 100% sure that it is dead. I do have another issue with this Jeep but I think I should save this for another post.
Thanks!

Welcome to the forum.
As for the oil leaks, try not to assume anything. I would clean the area first, perhaps put dye in the oil, and verify where the leaks are coming from. I cover diagnosing leaks in this article.

As for the replacement of the oil pan gasket and rear main seal. That may prove difficult. With a 4WD vehicle you have the front axle in the way of the oil pan. This makes removal difficult. You often have to lift the engine to remove that for replacement. With the rear main, you would need to remove the transmission and transfer case. Also, not an easy task. Especially when on the ground.
If you wind up needing to replace both seals, I’d recommend removing the engine to do so. It may be the easiest option in the end.
As for the AC, if you’re not familiar with working with AC systems, I’d recommend taking it to a professional to get diagnosed. AC work is often beyond the capabilities of the DIY. More info on solving those problems and a video on how the AC system works here.

Good luck and keep us posted.
