You ve probably already tackled the problem, but in case you re still waiting. The most likely culprit is broken rollers. Based on my experience they are probably in stock at the parts department. You probably should replace them even if one or both just popped out of the track (I can t imagine how without breaking). I just asked for the green rollers for the window mechanism" and the parts lady returned with a set a minute later. The job itself was relatively easy. I recall that you have to put things in the tracks in the right order to get it all to fit/stay, but I don t remember the specifics. It was an easy one-man job.
It s been about 5 years (and probably 70k miles) since I did the job on the driver s window of my 00, but I don t remember any significant snags in the process. There is a plastic sheet under the door panel that you can carefully peel and roll out of the way. Then you can reseal using the original glue. There is a foam sound baffle (may just be around the speaker area so I don t know if you need to pull that) that uses the same glue a little harder to pull without tearing, so I used an Xacto knife to cut the glue.
I highly recommend the twinsaabs. Com (AKA FixMySaab. Com) website for advice on any Saab DIY work! I didn t use the door panel page that I see is now available, but it looks pretty accurate. It depicts a newer model 9-5, but there are only minor differences.
While inside, you might as well check to make sure all hardware is tight. (I had a door handle mechanism loosen a few later, but it was, of course, on the opposite door.)
