If your clutch is slipping,this topic might help you, the compressor on the SAAB is almost identical
A/C clutch topic I followed it, and it worked on my sister's 1995 Mystique, which lost the A/C when hot. You can get a new clutch assembly from RockAuto.com. See if the compressor turns reasonably by hand. The Black Death is when the compressor is wearing out, and I imagine that happens a lot in hot climates where you have a/c on anytime you drive.
