If you want to remove the door card then it is a straight forward job, there is an inner part of the handle that needs to be prised off this then leaves the handle and switches for electric window clear of the frame holding it in, there are a couple of clips holding the plastic surround of the handle in the door card but it is quite easy to remove.
Remove the side panel furthest from the cable reel.
Ford Fiesta Mk6 VI 2002-2008 3 Door Front Seat Tilt Handle Lever. The first two steps can be done in either order, but doing them in the order I have listed below will prevent damage and scratches to. By trial and error, I have found a good way to remove the door panel from a 2002 Ford Explorer (and other similar years).
