The 12v socket in the boot space has stopped working.

According to the manual (sorry I know its bad practise to admit ever opening it) the fuse is No 63 in the glove box, which I have checked and its okay. I couldn't find any other reference for another fuse for the socket. I thought that there might be a fuse in the fuse box in the spare wheel well but unless I'm wrong there isn't.

Any advice or help would be appreciated. Updated- Waiting for a Scotland v England 6 Nations home win. 24th Feb 2018

It happened a few times on my car. I eventually found it was the thin metal of the 12 volt socket which was not making proper contact. Photo of socket here down the page: https://www.freel2.com/forum/topic33954.html Procrastination, mankind's greatest labour saving device!
