Always check the fuse first, but from your description it sounds like that may no be your issues. Always check out vehicle-specific forums for a general idea into the issue. Just take into account that this route is guess work and is not a proper diagnosis, and if you take it to a shop they wont care what the internet or friend's uncles' babysitter says is wrong with it.
If it comes down to wiring, if youre not experienced with such things then DONT MESS WITH IT. You can cause a hell of a lot more problems than you started with and Ive seen it a thousand times here at work. Wiring is one of those things its worth it to bite the bullet on, pay for a diag and repair at a reputable shop, and let them cover it if something goes wrong with their work.
