Having the title's air flow problem with my '99 (2000?) BPA, and experiencing a reluctance from my B-dealer to repair it, I thought, what the heck, I'll google it to see what insights I may be able to acquire from the web for a possible DIY project by a non-mechanic retired engineer (me). So finding this forum quickly, I was amazed and educated by a page full of really helpful comments, altho it all sounds pretty complicated and not likely a DIY candidate!
That said, I'll get to my (now revised) point. As a 20 yr owner w/only 74Kmi on my PA, that considering my soCal environment I really don't need all those variable directional settings...and come to think of it, I'd actually be happier to jury-rig a 'fix' that would just freeze the system permanently to the dashboard-only flow, which if doable, would also likely be a lot less expensive than repairing to a factory performance which I don't need (or want) anyway.
So that's it...I didn't see any post suggesting that option, so what say you guys? Anyone think it's feasible or not?
