If it's not the fuse or a loose wire I'd probably just botch it by splitting the 12V feed to something else, there's plenty of them in the car. I am a botch merchant do like customising my possessions though.

Probably easier than troubleshooting Peugeot electrics...

Did it come with any sort of warranty?

Lucy - get a Haynes manual for it. Or pull all the fuses out of the box one by one and continuity test them, then replace any that are blown! There might also be a hidden fuse box in the engine bay or somewhere with more fuses in it, not sure on a 206 but it wouldn't surprise me, seen it on quite a few cars.

*takes sweet*

Edit 2: 200, yay!
