A 15amp fuze in my car for the radio/interior light/etc. has blown again. It did this before and I would put new ones in and It would blow them right away too. But then about a month ago, I put one in and it holded till now. Now when I put a new one in it blows it right away. What is the problem with my car? I don't have the stock radio or back speekers so should I put a bigger amp fuze in? I don't want to blow the radio of wires or anything. Any seggestion would be great thanks!

 

Don't EVER put a bigger fuse in place of a smaller one, there is a reason why the fuse is rated smaller (wiring harness, gauge of wire used). If you can obtain a wiring diagram, you need to try and trace what components are powered by that fuse. A lot of times, there is more on that fuse than what the owners manual says.
