Last night, with the distribution blower set at its max, I went in and pushed directly on the screw. Sure enough the noise stopped. After shutting it down, I pulled up on the deflector far enough to wedge the gasket material directly behind the screw (what a bear that was!) I still need to apply some silicon to the screw and to seal the gasket material in place, but it seems to have done the trick (although it seems like a temporary solution to me especially if the gasket material wears out!) It makes me wonder if it would harm anything if the screw and/or the small section of the deflector were removed all together? Another solution would be to solder or tack weld the two pieces of the deflator together (Harman are you listening???) Then the screw could be safely removed? All I know is that whoever came up with that design should be made to sit in a room and listen to that annoying buzzing noise for 8 hours. That way he/she will put a little more thought into the next time they design something. PS Has anyone seen or heard from my dealer?
