ok.. well i looked into my fusebox and found out there was no fuse at all for fog lights so i put one in and now they work

they are tooo yellow though, icky. ill work on that later, maybe they will be super high beams... the possibilities!! well for the third fuse which is for :
parking/taillight right,headlamp cleaning unit, Illumination : license plate, instrument,control climate
ok when i looked in, this was fuse was blown. so i replaced it with the correct one, i forget the value but it was the white one, and when i put it in, i checked again later tonight and it was blown yet again. i am thinking this could be the cause of the license plate light not working, as well as all the inner lights and right brake light.... so what are the causes the the fuse being blown? can this be a diy project? any ideas would be appreciated.
