Sliding door not locking

[ariel badger]

My Multispace driver's side rear door is not locking with the fob. what are the possible reasons for this please? Thanks.

Dirty electrical contacts where the door closes?

Door contacts are clean and there is a voltage pulse on the meter when fob clicked, also there is a resistance on the door circuit, I guess I need to strip the skin from the door and have a look.

Can you bhear it trying to lock and failing, or unlocking again? if yes, it could be a physical blockage or wear.

Sorted, A little plastic clip had failed on the servo arm and the link had dropped. 2X1mm holes drilled and a loop of SS locking wire has sorted it.
