My left rear window will sometimes, when I hit auto up, go up all the way then drop down open about 3-4 inches. But somehow finally it will stay up all the way. I never know when it will do this strange thing. Can someone tell me what maybe wrong with it? All the other windows are fine.
Your windows just need to be resyncronised, you just have to push all the buttons down and hold them down for about 15 seconds and then put them up one at a time. My E280 kept on doing just what you are describing but then I was told about this process and now they run just fine.
