My wife has just rung to say the window glass has come off its runner and is now jammed with the front end somewhere inside the door. She is 180 miles away and wondering what to do, so I sent her to her nearest Ford dealer in the hope of a quick fix. Does anyone have experience of this, or know what might have heppened? The car is a 2004 TDi Elegance which lives outside, so the chances are that something has rusted.
