Have you got it on fresh air or recirculated when this happens. If it's only on fresh air you could have a leaf stuck to the outside of the intake filter.

Yes, you have to remove the windscreen wipers and all the plastics underneath them and you'll see the filter in front of the passenger's side of the windscreen.
