Jeff, I just did this on my '93 9000, so I hope this helps. If I remember correctly, you need to undo the bolts/screws holding down the evaporator case so that you can pull it forward a bit. Then bolt 'B', and screw 'A', along with 2 other screw 'A's, one on the opposite side of the electrical connector (it has the same clearance indent in the plastic), and the other underneath the metal gear housing. You'll need a dental mirror or something like it to see these. This frees the motor assembly (metal gear/motor housing + black plastic gear housing) from the metal mounting plate underneath, and you should now be able to pull it out to the left. When reinstalling, you'll need to power the motor until the recirculation drive shaft is in the 'recirculate' position, the flap itself hanging straight down in the 'fresh air' position, insert the motor assembly, and rotate the assembly counterclockwise so that the assembly mounting screws can be inserted (note that this also rotates the flap to 'recirculate'). This probably sounds more complicated than it is. Saab wants $280 for the motor assembly, but all that is likely to be wrong is some corrosion of the ($0.50 Japanese) motor due to water infiltration. I was able to disassemble mine & clean it with contact cleaner - it works great now. Also note that the recirculation flap is really 2 flaps: a foam flap which the motor drives, and a free-hanging plastic flap behind it. I'm not really sure what the plastic one does, except perhaps to allow greater air flow in recirculation mode when the fan is on high, and to restrict it a bit otherwise. On mine, the 2 flaps were stuck together (due to it being in the 'fresh air' position for a number of years), and when I rotated the flap during reassembly the plastic one came out of its hinges and dropped down into the evaporator case. They are definitely not meant to be stuck together since they have different hinge points. In any event, you can save yourself a LOT of grief if you gently free the 2 flaps from each other before trying to rotate the foam flap, otherwise you'll likely need to remove the glovebox & fuse panel and try to maneuver the plastic flap onto its hinges. That part took me as long as the rest of the repair....Good luck!
