I got a ed falcon and the drivers side window in the door is starting to rattle when going over bumps. never used to do this

any ideas on what i can do to try and fix this? are there any obvious signs of rubber wear and tear i should look for maybe a loose screw??

cheers

The glass may have jumped out of the bailey channel, or the bailey channel rubber may need replacing.

Remove door trim and check from inside. Also check for loose bolts x2 at bottom of glass.
