Help needed with Trunk Lock on Type 44

[Adam Jansen]

Went through the Bentley and it isn't helping
On Type 44 the central locking system is supposed to work all the doors AND
the truck lock?
My truck lock appears to be stuck in the manual operation mode (e.g. to open
stick in key, turn key push in)

I can hear something sliding in the trunk area when I unlock the doors, but
cannot find the problem

thanks
