THANKS for the info. I lucked out with my '96 XJ. It's OBD I so I can access it by key. We've been having trouble with a/c compressors staying alive. Everything has been replaced. Yesterday the CEL came on(first time since I replaced all O2 sensors and IAC)and a few hrs later the compressor started squealing then locked up. Got to be contamination from somewhere.
