Yep. Take the inside cover off comnpletely. Have the window wound down as far as possible. Feel up inside the door, following the guide of the winding mechanism - the upright that carrys the winding cable. You will feel the bottom of the window and then in another 1-2cm a plastic connection to the glass. The glass has a hole in it which the mechamism joins to via a plastic 'plug'. There is a locking open-ended washer (kind of like a plastic circlip) which you can pull off parallel to the window, its attached to the plug by a little loop of plastic. Once this is pulled off the window can be detached from the winding mechanism by levering it away and off the 'plug'.
I was replacing a broken cable in mine so didn`t take the glass out of the door, however its clear that removing the glass would have to be upwards through the frame.
Its hard to describe but its actually quite easy to do
