PEUGEOT BOXER SYMPHONY REAR DOOR

Hi,

The rear door catch on my M reg Symphony will not work so I cannot secure the vehicle at the moment. It seems to me that the vertical catch that locks the door is not locating as the movement is negligible and it is stuck in the 'up' position.

I have had a look without the panel but it is all a bit tight in there to see anything. Does anyone have a cut-away for this or has anyone had this problem before and succeeded with a fix?

All advice gratefully received.
