Have a 1998 320CLK which has electric windows that go down as normal and then take about half an hour to rise at about a 'mm' at a time...painfully slow.

The battery has been flat recently....would this effect the windows or is it something more sinister....battery has been re-charged and everything but the windows is working.

I'm also sure that I read somewhere that there's a way to reprogram the windows, ie holding down both window buttons and once down continuing to hold the buttons for a couple of seconds....any truth in this...I'm loathe to try as it could end up with me spending the next hour watching the windows rise by a 'mm' at a time
