Hyundai Repair: Excel head lights, light fuse, fuse box

Question
My head light fuse blows only when the car is hot but when cold it dont blow the fuse so after the car warms up the fuse for the head light blows any idea,,

Answer
The only time I've seen anything like this was when an underhood fuse box was rewired incorrectly after a collision.  

To find the problem, you should probably get the car hot and then check to find where the short may be.

If you reply with the year of your car, I'll look at the schematic and see what else the headlamp fuse may control.
