My fuse melts

Hello friends waiting for a merry Christmas, I wish you the best for 2013.

Well I spoke him about two weeks I got a message that I had a light transcera, and immediately then the ulimunation of the board and abroad was cut, the fuse was changed and the spotlights of the door were changed, and I lasted 3 days the taste and the fuse fuses it again. 24 hours, and again the spotlights of the Transcera Door Stop were melted again, and to vary now I got the message "Selector 4 Service" My truck is a Jeep Grand Cherokee 1997 4 x 2, 6 cylinders.

Something similar happened to me and it was because I had a cable crushed, it had been peeled and towards short circuit when it came to play sheet in some boat, good luck
