Yeah, it’s a good idea to change the cabin filter while you are in there - one of my least favorite jobs (I’m 6’4”, 235 and have large hands. I hate getting into small under dash spaces.) That said, it’s much easier than the driver side!
Accessing the motor isn’t too bad once you have the glove box out, and it’s highly likely that the stop arm on the spindle the motor drives is the culprit. Easiest way to check that is to remove the motor and see what’s up, as well as see if the levers move by hand.
Another thing to check is to make sure the motor is actually working. Easiest way to check that is while the motor is dismounted, but still attached electrically, manipulate the heat from LO to HI or do the self-test. You may get extra codes as the motor isn’t attached, but the main purpose of this is to see if when the motor activates, the brass spindle that would drive the mixing flap is actually moving. If it isn’t, a couple of screws will separate the motor proper from its gearbox, and you may have to press the small gear onto the motor spindle to ensure it engages with the gearbox. Contributor “dmz789qqq” did a write-up on this a few years ago - search the board for his tips.
Finally, I’m attaching a link to a site that has fantastic pictures and step-by-step for a variety of DIY Saab projects, including accessing the stepper motors. (While he discussed error 8, he shows how to access both the drivers and passenger side). Note that he had a friend make him the replacement parts he needed; nowadays they are readily available from site sponsors and other online sources.
