Where is the door locking fuse?

Where can I find the central locking fuse on a 2004 Nissan x trail 2.2 dci. Looked driver side under steering wheel fuse box no reference to C/L, also under bonnet battery side fuse box still no reference to C/L. Only door I can use is drivers door which opens with the key, other doors have no power going to them. The drivers door opens mechanically with the key, the rest open electrically but have no power, so it is a fuse gone but cant find it. Just need to know where it is.
