Synergie Sliding Door Stuck

[Gammy leg]

Chaps,

The n/s sliding door of my Synergie is stuck. I think that the link rod between the handle and latch may have stretched as it cannot be opened from inside or outside. Does anyone have a schematic of the internals of the door and/or information as to removing the interior trim panel. I'm guessing that the dispatch mechanism would be the same, but I really need to know how to remove the trim panel.

Thanks

Gammy
