Hello!

I need some help. I have taken my car to the Cadillac dealer several times and they cannot find the root of the whistle in driver's side window. Has anyone had any similar problems in a 2005 DeVille that could give me some direction? The noise is driving me and my wife crazy. Any thoughts or suggestions would be greatly appreciated.

Thanks very much!

Larry

An easy way to troubleshoot if it's the window is to tape over the seal between the glass and door frame with a low adhesion tape like the blue painters tape on the outside of the car. Then take it out for a drive to see if the whistle is gone. You can play around with this concept until you figure out where the air is coming in that's causing the whistle.
