hi mate, i have a daewoo lanos, and had very similar problems.
There will be a Circa clip (or C clip), but it is tucked very tightly into the window winder.
I had to put a screwdriver between the winder and the panel and lever the winder as far to one side as possbile, then use another screwdriver to lift the clip off.
It is possible,just takes a bl**dy long time, and i promise it goes back together a hell of a lot easier!
