On the C280, the driver's side air vent barely lets any air out of it.
I would think this would be a vacuum problem, but the side vents are not vacuum operated. No matter what position the I put the air flow, air comes out of the side vents. So that is ruled out.
I once took off the speaker and vent cover housing to see if I could determine problem, but no avail. Wasn't clogged or anything.
Anyone have any idea? Thanks.
