Unhappy Strange Whistle (not side mirrors)

Ok, I know people have written about this sound coming from the side mirrors, but mine doesn't seem to come from there.

It usually happens at highways speeds (70mph), with a strong headwind.

To me it sounds like the window corkage. It's very loud and seems to be coming from the front windscreen. It comes and goes with passing gusts of headwind.

I've been to the dealer who has 'adjusted' the gussets in my side mirrors, as he said it was this ... but I still get the whistle.

Anyone else have this problem?

Could it be your wipers making the noise?
You could pop them off and take a test drive or just turn them on when you hear the noise and see if the noise changes
Another thing you can do to narrow it down is to cover part of the bottom of your "windscreen" with some light cardboard to eliminate one side or the other and move it around until you found "the spot". Some duct tape might be helpful here.

Good Luck!

A few of us have had that problem. We think it's the seal around the window. Mine happens at a higher speed, but a took someone for a ride who owned a body shop and he thought it was the seal. I've had it happen going highway speed and a semi comes the other direction. The wind of it passing will make it happen for a second. Sounds like a broken reed on a sax or something like that.

Mine does it too around 80mph. I noticed that if I rolled down either of the front passenger windows about an inch, it makes it go away.......but it creates a new wind noise from the window being down. I, for some reason, thought it was the roof rack. I noticed the noise will occur at 80mph on some days, and 75mph on others. I just figured it had to do with "air quality". I was gonna try to move back the roof rack a few inches to see if it helps.

Ours does this as well...but only when we have the HVAC set to recirc. When we have it to fresh air, it seems as though some pressure inside the cabin eliminates the whistle.

When on recirc, I'm guessing that the prssure differential is making the leak more pronounced. I dunno if its allowing air IN or OUT. I'm gussing out since the cabin would be a higher pressure zone than the moving outside air.

Just something to think about...

Thanks guys, and thanks for the link Caddy Daddy ... sometimes hard trying to figure out what others might call it

Ok, for info:

I don't have the roof-rack on, but this still occurs.

I think I remember trying the wiper blades, but I can't remember. I actually replaced them last night (under Caddy Daddy's suggestion) with Bosch Micro Edge Excel's ... so I'll wait to see if that's the cause. I notice the arms on the Bosch's have less surface area ... so hopfully they'll stick to the window a bit better at high speeds ... and maybe not make that noise

I haven't tried the HVAC set to fresh air ... so I'll give this a try.
Also haven't tried windows down ... so will give this a go too.

Peaty, excellent description: "Sounds like a broken reed on a sax or something like that.", that's EXACTLY what it sounds like. I've also noticed it for a second with a semi coming the other way.

Right-o ... off to work

I'm getting a brand new window because of mine! At over 80mph (or slower with a good headwind), I can push out on the top edge of the windshield right by the rear mirror and recreate the sound at any time.

The dealer said that the sealing holding the window on has a small gap in it alowing air to come in. They have to remove the windshield, re-seal, and replace. By themselves they couldn't find the problem and said nothing was wrong, but I had a tech ride in the car with me while I pushed on the windshield...boy was he surprised!

Ok ... well I went on a long highway speed ride over the weekend (at about 11pm on Sunday night) and as it turns out, it is the gusset around the windscreen!!!

I pushed behind the rear-vision mirror when I was approaching 'whistle noise' breakout and could make it do it with just a little pressure applied ( thanks irmiger )

My local dealer will be hearing from me TODAY!!!

Does anyone know of a TSB on this? I know I'm gonna have to show them ... and I don't really want to have to find a place to do ~70mph in Houston on a weekday morning

What was the TSB for about the dimming rear-view mirror?

Just a dealer adjustment to the electronics in your mirror if it either didn't darken (leaving you blind) or darkened too much (well...also leaving you blind ).
