My 03 discovery has developed a rattle vibrating sound right where that clip is on the driver door window. You can put your finger on the metal part of the door and feel the vibration the worst right there. I did a visual inspection of the door and nothing looks wrong. It vibrates only at 50mph and pushing on the window does not stop it. Anyone else have this? Car was never In a wreck this just randomly started last week

Have you tried holding this down? It's a plastic piece that bridges the gap between the roof ridge and front window.

 

I haven’t since I hear it most at like 50. The vibration seems to be more than just a loose piece of plastic but maybe

 

Or possibly loose exterior A pillar trim piece. Mine has one loose clip and makes a vibration only at speed that could easily be confused with a door sound.

 

Here’s the thing it’s not much the sound but the feel I can put my finger on the metal door frame and feel a vibration along with the sound. Which is why I think it’s more than plastic

 

Should be fairly easy to rule out the plastics... Just go out and see if you can make them move with your hand.
