Well the compressor on my 96 Grand Cherokee died yesterday. The clutch was screaming like a wild animal, so I shut the engine off and turned the compressor by hand and it felt like the bearings were bad. I haven't opened up the system yet, so I don't know if there is any debris in the system from the failure. My plan is to replace the compressor, the condenser, the liquid line(with the orifice tube), and the accumulator. That leaves the evaporator and the high pressure line from the compressor to the condenser. I want to avoid flushing anything. The evaporator is only a year old so I think I will just leave it alone and use some compressed air to blow out the high pressure line. By the way, the compressor and the condenser are the originals and after nearly 13 years and 191,000 miles I guess that's not bad. Can't say that about the evaporator, though. I will be ordering the parts from this site, using nylog on the o-rings, and DEC PAG 46 in the system. If anybody has any suggestions on how to make sure this repair is successful, I would be very thankful.
Should not be too much debris with the Denso compressor. After pulling the accumulator drill a big hole in the bottom of it which will allow you to drain and check the condition of the oil.
Thanks Tim. For comparison's sake, do you have a new compressor for a 96 GC V8 or just the rebuilt one?
ghiotom, thanks for the support! We will work on getting the order out Monday!
Definitely consider pulling the OT and checking for debris.
Any sign of debris and you will need to flush. Universal In-Line Filter is a good insurance policy as well.
Why the aversion to flushing? From the sound of thngs, you'll only need to flush the evaporator and discharge line... not that bad. An inexpensive Mastercool AC Flush Kit should do the job fine.
Any other questions or if you run into problems, you've come to the right place.
