Light fuses are melted in Seat Cordoba

I have a problem, I have a Seat Cordoba 1.9, I put the fuses of the rear antinieblas (nº 10) and the light of the enrollment (No. 3) and melt at the moment. In addition, the trunk light is fixed, it does not turn off when the trunk hood is lowered. What do I do? I don't have much idea, I have already reviewed the bulbs, the headlights have no moisture, the cables that are seen do not seem to be bad.

Thank you

Hello, look at the problem you have to have it in the piece of cable that passes from the body to the porton looks at it well that you have peeled cables and make contact with each
other and the fuses melt a greeting ..
