Seems whenever the moonroof is open and speed is over 45 or so the noise generated by the wind deflector is pretty loud, and gets louder as the speed increases. When you reach up and hold the spring-loaded deflector down it's much quieter, however puts more wind back into the rear seat.
But being the troglodyte that I am, and we don't have people in the back seat very often I made up a proto-type of something that works.

This is a piece of plastic salvaged from an old refrigerator egg tray.
I cut out a piece that's 3 inches wide, 11 inches long and just under 1/8" thick. Using a heat gun that I usually use for shrink tubing on electronic projects, I bent it into the shape below. The below pic is just a prototype and I hope to bend up something more "Lexus Like" later. Maybe I'll use the triangle pieces around the mirror.

Whit, I love your ingenuity, and that's exactly the kind of thing my Dad used to do .................

.............. but I have to tell you that just cracks me up!

 

Yeah, I hear you. Not much for pretty, but hell for stout.
As I said this is just a model, sure quiets things down when running down the highway. I get fresh air and can still hear the radio.

Why not just wedge the deflector's linkage so it doesn't pull up when you open the sunroof? I doubt it would make an audible difference at lower speeds anyway, and since the annoyance is not going to go away at high speed, then a semi-permanent, elegant solution like silicone sealant for instance, would keep the deflector locked down but would still allow it to be released at resale time.

 

Still getting wind noise from the sunroof area.
What can I do?

 

Actually I considered that first but couldn't comfortably find a place to put the 'wedge' that wouldn't interfere with the track/rail mechanism.
I'll take another look, as my gadget looks pretty klutzy and could cause problems if the roof closed and the gadget was still in there.

Well...there was more clearance between the sliding panel and deflector in the recessed position than I thought. I installed a 3/8", Truss-head sheet metal screw immediately next to the deflectors trailing edge, with the screw head overlapping, and it seems to work... so far. I may have to add another screw as it takes a good bit of effort to pull the deflector all the way down.

(FIY - A "Truss Head" screw is a very shallow screw head with a larger than usual diameter.)

Great idea; I'm glad it worked out for you... You might want to seal the top of the head for corrosion resistance.

 

Good point. The screw actually has a flat black plating on it. Looks like the camera's flash made it look like stainless or just steel, but I'll dab some black nail polish on it as cheap insurance.
