Hi I've been noticing alot of wind noise while driving my 99 D1 on the freeway. Most of the sound is coming from the top somewhere near the front sunroof. The second area of noise is coming from the drivers side window area. Is there something I should check to fix or replace? Thanks!

 

Do you have a roof rack?
Check and make sure your front sun roof is all the way closed, look at it from the top to make sure you haven't rolled a seal.
Have you looked at the door seal on the drivers door, cheek to make sure there are no tears or flat spots.
