I did a search on this topic but there were no conclusions about the cause.

Got my tc in October and there were no problems. But the last few months I get a high pitched whistle at 50 to 60 mph. Sounds like it's wind coming from the front of the driver side moonroof or the front windshield - not really sure.

I thought it was an air leak between the rubber seals and the glass of the moonroof. So I lowered the driver window and pressed down on various parts of the moonroof while this happened. But it doesn't stop the whistle.

Also, whenever it rains or my car was still wet this whistle never happens. Maybe the moisture seals the air leak?? (No moisture or water leaks into my car.)

The whistle happened just occasionally at first, but now it happens almost everytime I drive on the freeway.

Please help if you have experienced this problem or have any ideas how to solve it. (I took it to the dealer and they serviced the moonroof for the rattles but it didn't help with the whistle.)

Thanks.

There was a post about this same situation before on this board . The owner had to have the seal around his winshield either replaced or the glass reset . One of the two , I am not sure if you do a search for it you will find it . This was a month or so back though . After he had the seal replaced/reseated the whistling stopped
