hello mate... right .... inn short for now mate... as it was a long time ago i did this... also please dont hold me responsible for inaccurate info! :/ its a vague memory.. but i hope it helps a little at least.
all from memory aswell im afraid... undo all bolts holding door card on... including ones under the handle. (prise off with small screwdriver wrapped i tape )
u might also have to prise the door card off as its also stuck on with silicone substance, and poppers things...
once off youll notice its still attached by electrics.. however they all have clip plugs to it can be fully taken off.. as far as i remember, i didnt have to take any locking system apart for it a\t all just slipped it through the hole i the door card... from there... the metal plate is f**king awkward, as to get it off you firstly need to tape the window at certain point... ( from this bit onwards mate i watched a clip of youtube how too.. but i cant find the vid now
) again this is all from memory so dot hold me responsible in any way... there are two big gromets on the metal plate which when undone reveal the sliders for the window.. (if window is done right up, bring it down untill two clasps come into veiw,, this is where you need to tape the window in to place, as when this is undone, the window will fall!!!!!!
from here the plate as i remember has to slide up the door outwards... i think!!
really sorry i cant be of more
help... it was a long time ago i did this and unfortunatly didnt take any pictures... have a butchers on google and youtube for tips
thats where i found most of mine!
also if your anywhere near kent i may be able to lend a hand...
