w124 window trouble...
Alright, a few months ago, my rear right window started making this funny noise when rolling up or down, sounded like a piece of metal was rotating around and around, hitting stuff inside the door. Well, soon after, the window assay "exploded" in the words of my mechanic, resulting in a $130 replacement of the window assay. Now, my front left window is making a similar metal on metal sound. When you push the window up or down button, the window moves, a little slower than usual, but it makes this metal clanking noise. any ideas what this is? Thanks.
