I have just replaced my battery in E320 2000 and eversince the auto up down function on the windows will not work. I have to hold the button continuously to get window up and down. I have checked a few fuses and seem ok but can't find the specefic fuse for this function...any ideas

I had the same problem. After a few days the rear windows started to work and then a few more days the front started. There is probbly a way to reset but if you don't mind a few days they will come back to normal.

Thanks but went by Mercedes and asked and they said all windows had to be reset..here's how.
Press button to get window down and then press all the way and hold for 10 seconds ,do the same in the up position and for all windows
It worked.
