my ml`s driver window rattles when i am driving i have given it top MB and cliamed they solved the problem bu when i got the car back a few months ago i noticed the window problem was not solved and to be honest i really never got much time to go back and complin about the service, but i am now think og going back and sorting this probme out becasue the noise is not so loud but annoying so i have to keep the window only fully open or a few inchs but not halfway. any ides can i repair this myself as a frien said you have to tighting some screw.......
