Hey First and Boulder called my dealer today (Scotts)told them that i cant go on much longer with the marker light noise he told me hes calling GM to find the right fix if there is one and is not going to put 3m or something without their permisson so I will let you guys know what happens if they tell me live with it I will want a name to talk to GM or Hummer and get to the bottom of this Thanks for the info First I would have thought the foam would work. the windshield is so flat when driving the wind justs goes right under the lip. I cant believe this is happening and these dealers dont have a clue you would think that they gave these lights a dam wind test before releasing them to be installed
