What causes this fuse to blow? I am up to a twenty amp fuse. I had a fifteen which lasted less than two weeks. I think the previous owner had an aftermarket stereo in, I found some bundled wires underneath to the left of the steering column. I fixed one that was not connected good, but I continue to blow. I do not know if these have anything to do with my situation or not.

 

Have you traced the wires? And if so, where did they lead?

 

hopefully you arent replacing the fuse with a bigger one then supplied from the factory

 

last 2 people pretty much summed it up.

 

replace the fuse with a jumper wire and you'll find the short when it catches on fire
