I think for the compressor I will find one in a junkyard for 30 bucks instead of replacing the clutch and or bearing. To change the compressor out I obviously have to disconnect the pressure lines but first how do I drain the system?

ok found some new things today. No junkyards have compressors around me so I havent gotten one yet. But I hooked a bottle of freon with the psi gauge on it to see the low side pressure and it is around 80 psi which is not good. Also the bearing in the compressor is shot, the pulley was wobbling back and forth 1/2 an inch. And the air coming out isnt cold and smells HORRIBLE. So far im thinking to replace compressor, and check the orifice tube for blockage(If someone could tell me where that is it would be great)

I'm changing the compressor, drier and orifice tube later today. Before charging the system I have a vacuum and gauges to get the moisture out. Before I do this should I flush/clean the evaporator or condenser?

Any Luck

Any luck changing out the parts? Did it solve your problem? I have a 97 TJ and I am having the same problem. I have a slow leak, that I keep filling, but when I get over 45 mph no more cold air, it keeps blowing out the vents just hot.

Yes after the compressor, accumulator and liquid line were replaced the issue was solved. I have driven around 1k miles since and no leaks AC blows cold. I also used a $12 AC vacuum from harbor freight prior to refilling with r-134a
