'98 Jeep Cherokee A/C help

Where in the world do I begining to look for the A/C low-side post? I have a '98 5.2L 8v Cherokee! Any clue? I have NO experience with cars!
Thanks,

I assume you have a Grand Cherokee with a V8.
I don't know where the low side post is exactly, but it is usually right next to the Compressor. Try posting in the Grand Cherokee Forum.

Moving to Grand Cherokee forum for you.

I'm not sure exactly where it is, but start at the compressor and follow the hoses. You should see two different places with valves in the line. When running the AC, the low side will be the cold one.
