How much would a fuse for a sun roof on a VW Golf cost?

I tried to open the sunroof on my VW Golf and the fuse blew. I need a new one but don't know where to get it or how much it costs. Any help would be appreciated.|||You get fuses at a parts store. They are usually in blister packs hanging on a wall in the lights dept. You can get a assortment for your car for about 3 or 4 dollars. Pick out the one you need and keep the package (it's small) in the glove box for the next time you need a fuse.
