Good used unit -  4868659 SD7H15  This is the good quality SANDEN Compressor. I removed this personally from a crash damaged 1998 Saab 9000 CDE that was crash damaged and still had working AC on removal.  This is a good used compressor.  Please be sure your 9000 uses the Sanden Compressor and not the trash SEIKO-SEIKI.  If you have a SEIKO-SEIKI compressor you have either a broken compressor or if it somehow still works a ticking time bomb under your hood.
