Everytime I replace the 15amp fuse for my instrument panel lights, it will burn out like 2 or 3 days later. Really weird.

I've tried to put a 20amp fuse instead of the 15amp but same thing, still blows after awhile. All I have to do I put a new one in and it works great. Got in my car tonight and noticed the lights were out immediately, so I replace it with a 15amp fuse and they came right back on.

Why is this happening!? '93 XJ Country

The 20amp fuse that was blown that I noticed tonight

 

You have a short circuit somewhere in the system.

Anything else like marker lights, park lights etc not work when that fuse blows?

 

Everything works fine except for the instrument panel lights I believe

 

Believe, or know......
