I did this on my 2009 9-5 Aero this past summer. Got a Sanden compressor and a Nissens condenser. If you don’t have the Saab Electronic Pats Catalog downloaded, you can go to eSaab Parts and see exploded views with part numbers. I got the compressor from AutohausAZ.com. The o-rings and condenser from eSaab. I rented a vacuum pump from Autozone and refilled refrigerant myself. All works great now. I’m in Chandler, AZ if you need help. IMM Auto in Tempe does great work on Saabs if you need it done professionally. I have aTech 2 if you need a scan anytime. I also have a 2007 9-3 that I’ve done a fair amount of work on including engine swap, fuel pump, brakes, and ECU cloning. Here are the cars:
If I can help, let me know.
