Windscreen demisting

[BAZZER1]

Hi Guys
I have a problem demisting the front windscreen of my 2002 W210 E Class e320cdi Estate. It would appear that the two front windscreen dash vents are not working even when the fan is turned to maximum, The side vents are working ok, I have followed the setting instructions for this in my handbook but still not getting air pressure from the two top screen vents to clear the screen, I have only just noticed this, Has anyone any idea as to what might be causing this please.
All advice will be appreciated.
Many thanks
BAZZER1

First check would be the cabin filter.
Just remove it to test.

Thanks for your reply Ted, do you know where the Cabin Filter is on the 2002 W210 Avantgarde and how to remove and check this please.
Thanks
