Auto Parts: Central Locking, fuse box, front doors

Question
The central locking for the 2 backs doors on my Vauxall Vectra does not seem to be working.  COuld you please tell me if this has anything to do with a fuse ???  If so what is the symbol in the fuse box relating to the centrla locking.

Thanking you

Answer
Here's the questions that come to mind:

Do both front doors lock/unlock properly?

Do the back doors lock/unlock INDIVIDUALLY just fine?

OR

Do those doors NOT lock/unlock with the switch at the driver's door?

If the front doors lock/unlock fine, I'm pretty sure there's only ONE fuse for ALL doors.  So, try and isolate the problem with the questions I have posted.  Get back with me and I can help you further.
