Hi Andy,
when I take the door opening off there is just an empty hole, no plastic housing in it for a motor to sit into.
It appears that everything behind the door seems to have been taken out....

plastic housing, motor ect
I'm at a loss because there are no garages here that deal with crossfires
It looks like all the parts may be the same as an slk, if this is the case I may be able to get them from a salvage yard but still not sure where to get it fitted
