Vogel-Pfeiferl / Bird Imitation Whistle: Press your hand up against the windshield to stop the whistle howl: it worked!!

So I was laughing with glee as I could stop or slow down the windshield whistle. I read on some forum how someone had to press their hand up against the windshield while driving...
Finally, I realized one day that if I pushed on the top of the windshield when it was whistling, I could change the pitch.

Sure enough it worked! I had to push directly under the rear view mirror and then when I pulled over and taped both sides of the top gasket around the outside of the windshield - PRESTO - the loud whistle was finally vanished...

 Then came the epiphany... the whistle was coming from the space underneath the top windshield molding and the roof of the car, not the windshield itself.
So that's why I put tape on both sides of the moulding just to be sure.
 Another "party-horn-in-the-windshield" sufferer here. Like the others, the noise started just after a recent windshield replacement. The installer made a big deal of knowing how to remove the a-pillar side garnish without breaking the clips. The first call back, he just pushed down on the garnish. The noise came back, so I siliconed the small gap in the bottom edge of the windshield thinking that was the issue. That didn't fix it so we called the guy back out again and he siliconed the seals on the side garnishes. Yesterday, the party horn was back louder than ever. It seems to come out in warmer weather at between 50 and 60mph. That evening on the return trip, it was silent.

So, now I've found this thread. I washed and dried the windshield area thoroughly and siliconed the top edge according to the Tech Service Bulletin.
 Yep that was precisely my approach - I have black gasket sprayed along the side A Pillars - "Mr. Right" - it looks terrible but I like the raw run-down look.

I even put window expanding foam sealant to fill in the holes at the ends of the Cowl - where they are soft rubber flapping. That did NOT fix the whistle! haha. So I took out as much as I could and painted the rest of it black...
THANK YOU THANK YOU THANK YOU

I had my windshield replaced last year and mine just recently started whistling. It only does it in hot weather. I can turn on the wipers and it doesn't stop, but if I spray the washer fluid, it will stop for a while. I have siliconed under the lower edge of the top strip, but never thought of siliconing under the top of the strip. I also sealed the sides of the windshield and along the bottom with silicone with no luck. The damn thing was driving me crazy.
 Yes it's true that sealing the other strips first actually made the whistle WORSE!!
At higher speeds lateral airflow across the the upper edge of the upper windshield seal causes lift; the seal edge rises, air flows into the channel, and the seal drops. Repeating at high frequency, the seal acts like the bird whistles (see image) I bought as a boy for 10 cents ($0.79 today's money).

Depending on wind velocity, the age of the seal, and the hood deflector if any), the sound can vary from a low rattling duck call to a chirping whistle.

Sealing the other edges of the strip without filling the center of the upper channel, can restrict make-up air supply, and aggravate the problem.
And this:
When driving at highway speeds, I press on the top of the headliner near the middle of the of the windshield and the whistle/party horn stops. Clips look fine to me.....silicone?
Place the Vogelpfeiferl on the tip of your tongue and soften it. Then press it lightly against your palate behind your teeth with your tongue. If you then make the right sounds with your teeth closed, it will make the bird noises.

Szidäh szidäh szidäh dit! The Vogelpfeifer

Not far from the Bavaria, Oktoberfest is a great time to get chirping – and powerfully at that. The Munich Vogelpfeifer (bird whistlers) have their stand here and provide good entertainment.

You will have to place the round part to the back, exactly as on the front picture of the video, then put it up against the palate, press gently with your tongue, blow with a TSCH.... sound, your whistle will sing.

 ; just stick it up to the roof of the mouth, do not press your tongue against the whistle; it needs some space to allow air to run through.
