I have just fixed the same problem with my '97 9000CDE. After cleaning the bearings, a small dab of waterproof grease on each end seems to have fixed it. I also had a problem that the motor was not starting reliably, leaving the aircon unable to determine cabin temperature. It turned out to be one of the capacitors on the motor circuit board, which was replaced for 19p. There are actually 4 connectors for the unit - 2 just power the motor for the fan, and the other 2 connect the thermistor to the aircon controller. The thermistor still works when the fan is broken, but it is only getting a sample of static air behind the dash, so the type of air you get from the system (hot or cold) will probably depend on the outside temperature more than anything else. btw the best way to get the motor out of the dash (I have done this about 20 times now!) is to remove the covers for the sensor and the one next to it, poke a finger through this gap to push the aircon controls unit forward and out of the dash, then through this hole take hold of the sensor behind the dash and prise the clips top and bottom with your other hand ( you should have all 3 hands in use now!). You will now be able to manipulate it through the large aircon controls hole to remove the connector. I did a lot of searching the web to find an alternative part, but drew a blank. Mine is not a Bosch part - it is marked Saab but made in Japan by Jeco. I just refuse to pay Saab prices for things that can be persuaded to work a little longer (like the flasher unit with dry solder joints).
