Any tips on what to look at and what to do? It sucks picking up girls and you have to drive with the windows down. Thanks in advance

Most likely the compressor. I've been told i needed mine replaced and that it was a common problem, just never got to doing it..
Or does it just need a recharge?

That is one of just a few things I leave to a shop to do. I have the gauges but don't have a way to evacuate the system or check for leaks so I just leave it alone.

First check to see if your compressor clutch is kicking on. Chance are that its not kicking on. If you have or can barrow a set of gauges, hook them up and check to see what the pressures are. If your low side(Blue) and high side (Red) or at zero then you have a leak. The low side pressure should read somewhere around 48PI and the high side should read around 175PSI. If you have the pressure then you have a compressor/ clutch problem. It could be electrical such as a fuse or mechanical then you would have to replace the compressor. Now if your pressure is at zero the you have a leak. Check all your connections, your condensor, evaporator, reciever dryer, and expansion valve and look for an oily substance. That will give you a general location where the leak is. Also if you have a leak you can always go down to the auto part store and buy some refrigerant and dye for the a/c system. Add them both and let them leak out. It will make it a whole lot easier to find the leak. I hope I was some help.

I think it has to be a leak because I had it charged. The AC worked great but then it started running hot about 5 minutes later. So does everyone think that its just a bad leak?

Its must be a decent size leak. If you turn off your Jeep can you hear a pssssshh noise. Start feeling around you a/c hoses and see if you can feel refrigerant blowing out. Or you can go to the auto part store and buy a UV leak kit. It will show you where your leaking.
