Vent selector knob stuffed

[TheInterceptor]

As the title suggests, the knob is buggered.
Its basically stuck on blowing onto the windscreen, turning it doesnt do squat.

Has a connection come loose or broken?
The dial itself has packed it in or..?

I did have that part of the dash off (nothing was disconnected), pretty sure i havent done anything to it though, come to think of it, its pretty hard doin anythin behind there considering there is 10 odd cm of space to work in.. :S

Anyways, does anybody have any idea on whats goin on with it?
btw the car is an AUII

And a quick question so i dont start a new thread,
Is it illegal to have red LED plate number lights??

Cheers!
