Thus far the freon levels have been checked, a hose that was leaking was replaced. I have read that it could possibly be the brake booster check valve line, of which I have a picture. The other thing is the ac relay switch/cooling fan switch. I'm not sure if this is the same part or two different parts. I also don't have a clue as to where they are supposed to be installed. I need some advice and also a diagram of where the parts are located. 2000 xj .Thanks
__________________I'm going to replace the AC relay and see if this solves the problem. I know it's located on the passenger side in the black box,but I don't know which one is for AC. I also read where it could be the cooling fan switch,but I've got to research some more to find out exactly what this does....LOL. This guy is trying to convince me to replace the entire system for $700 including labor,but I think he's trying to rip me off.

Hello. I've got an issue with my AC in my 2000 xj and Jakbob said this was your area of expertise. 'm having an Ac issue and I've read several different things to check and wanted to make sure I'm doing the right thing. The AC is very cold when turned on, it will run for 30/45 minutes and then the air gets warm. Sometimes if you allow it to keep running it will get cold again in about 5/10 minutes. The other alternative is too turn of the air ,open the windows for a few minutes and then turn it back on. It will once again be ice cold.
