I just bought an '04 Galant, and everything is great except when i get to about 40+ mph there is a loud whistling sound from the top corner of the passenger side window. It sounds as if air is passing through, but you can't feel it. Just the noise.. I took it to a local glass/body shop and he couldn't figure out what it may be. Any ideas?

 

You probably need new weatherstripping, I have the same exact prob except on the driver window. Anyone know the cheapest place to buy some?

 

The Dealer or a Wrecking Yard.

 

Yep, it will be real cheap at a boneyard (auto salvage yard) and it may be as good as the one currently on your car if you are lucky.

Weatherstripping...if you were getting water in the car too at the point where the whistling is coming from, I would say it could be the weatherstrip. But if it does not get wet when it rains, it may be that the window track needs to be adjusted.
