Have read postings on this in the past, but can't remember the answers, or find them.
My 406 started making a whirring and ticking noise (constantly) from the passenger footwell yesterday. The ticking (almost like a plastic cog jumping) seems louder today. Sounds like some kind of motor in the ventilation/aircon system? It does not seem to be affected in any way by any of the ventilation controls/buttons.
What is it, and how do you fix it? thanks, John
