Ok so I have a 1998 jeep xj 4.0 and my jeeps ac works amazing for about 30 minuets then gets warm and the compressor stops spinning and gets warm if I turn the ac off for 10 min it comes back cold so I added some 134a and it made it better should I add more or get another compressor? Thanks for the help

 

was having the exact same problem yesterday, they change something in the fan clutch it cost me 50$ here in Dubai.
easy fast fix don't worry he put screw driver on the AC compressor pulley and boom it works again then he knew its something in the clutch
In my opinion your compressor is fine and well work for loner time (that what he told me) just go to a good electric man and he well do it .

 

sound like a shim may of been removed from clutch heat from engine causes clearence to change ,first thing is get pressures checked most places will do this for free...then go from there

 

Thanks for the answers guys I'm going out to work on it now I'm going to look for an adjustment on the clutch I guess

 

I gave up after a lot of time trying to fix it and took it to my dads friends shop it was a bad ground for the ac 120$ and fixed thanks for the help though

 

Probably for the best. AC system is hard to DIY.
