A short to ground or a high amperage draw, you need to check the amerage at that fuse if you have a multimeter. If the draw is not more than it's supposed to be you likely have a short to ground. Use a test light and connect one side to a 12V + source, then touch the fuse with the end of the test light(even though it is blown)(top of the fuse has two little windows on the top of the fuse) and if it lights up you found which side has the short. Then you need to trace the wiring.
