hi all
I have this strange problem with my AU series 2 forte. Whenever I have the fan running on the 'face' setting it will come out of the vents as normal until I give it a bootful then the climate control changes to the 'feet' position then gradually it will return to the face position with a slapping sound. Has anyone else had a similar issue? And if its something simple like a vacuum leak, where would the problem most likely be?
any help would be most awesome.
