air direction knob

[THE MEZMERIST]

Hi, I am new here, first heard about the owners club as a child, my sisters fella had an old mk11, loved the smell of it. Any way i wonder, has any one had a problem with the blower direction knob, about a month ago it stopped working and would only blow air on the screen, after a few days it went ok, but has now done it again, is this the knob or an other fault, whilst it better to work on the screen I would like some choise, and is it not a drag that the road tax on a 2.0 petrol is such a rip off, any advice commnts on the 2.2 turbo diesel would be appreciated.

many thanks for your time.
