Search this board for 'air distribution,' you're not alone. This seems to be a design or engineering flaw. I'm not sure I've seen any threads with a confirmed, permanent fix. There are a few possible issues--likely the distribution housing/vents themselves sticking due to inadequate clearances that eventually breaks gears/levers/arms controlling the distribution. Possibly failing motor that actuates the levers/arms that control the distribution needing some lubrication. Not likely the ACC unit itself though. The distribution box is sort of one unit, not something with replaceable parts (see diagram), and if you're in that far you may as well just swap out the entire thing with a good used instead of chancing a repair. I never was able to completely fix it on a '99 Viggen (no longer owned). Any attempt at addressing is going to involve getting deep into your dash, and likely that of a donor car. Good luck!
