Hi My daughter has just bought a 2007 SLK 200K, I noticed today that the rear 1/4 light window does not seal correctly against the door main window, there is a small gap where the main door window does not touch the rubber seal, it is worse on the drivers side. It is as if the window needs to rise up more towards the door. Does anyone know how to adjust the position of the 1/4 lights and is it a DIY task. Any help greatly appreciated. e-mail address for any info is firstname.lastname@example.org. Thanks.
