Noise

From : michael greenwood

Q: i have a high pitched whistling noise on the drivers side once i hit 25mph or so. its on a 2003 quad 4x4 slt that i purchased about 3 weeks ago. it sounds like its coming from the mirror flip up trailer type but i cant be sure. its only audible with the window down. anyone else with the problem and a quick easy fix apart from keeping the window up g. its a very minor annoyance but an annoyance nonetheless. thanks. mike .
