It's been several months since I had my Carnival serviced for the wind noise issue. I wanted to wait and see if it was really fixed. I'm happy to say it's 90% better than before. The dealer replaced three different weather strips on the door and added some foam backing to the weather stripping that sits against the driver side window. See the pictures below.
Replaced three weather strips around the door.
Adding foam backing to this weather strip (so it seats more firmly against the window).
This has mostly fixed the wind noise issue where it sounds like your window is slightly cracked. It's not 100% gone, but way better. Hope this helps.
