biacs

As it is now summer time, I wanted to revisit the age old question of the auto vents articulation. I know its certainly a 'can live without' feature. I just like to tinker and like to have everything working.

In my case the vents will travel left to right and then stop. So I know there is still some hope. Has anyone seen or posed details or a video on how to grease these things up? Is there a replacement motor?

Just out of curiosity.....
