There should be covers over the drain slots, thin long clamshell looking devices with the opening facing backwards.
If they are missing or loose you will get the wind noise that you are describing .
Nearly drove me crazy until I figured it out.
They are slides.
I looked and don't see anything like a drain, see picture.looking a drain
After I looked again I think I can see light at the lower bottom where the vertical rubber should meet the bottom rubber seal, the light is about the size of a pencil point which could be the problem. Both side look like the gap between the rubber is the same however I don't see the light on the Left side.
I think I'll get out the fix all duct tape and tape that window to see if that stops the whistle
Again thanks for the input, it may have cured the problem
