WIndow Closing
I am asking this question here because w209 has similar mechanism 9maybe even the same hardware) becuase of the pillarless design.
Can someone help? What went wrong?




To fix this, de-sync the window (easiest way is to remove the fuse for a minute) and then properly re-sync. Just be careful when lowering the window that you don't hold it in the fully-down position. My suggestion when syncing windows is to just lower the glass half way, so you don't accidentally sync in the down position. Then raise it and hold the switch for 5 seconds once it's at the top. If this doesn't do it, and the window otherwise moves freely up and down, then it's likely a bad controller.
