1993 Cadillac Deville FUSES

Both installing a higher amperage fuse and jumping it with copper wire are very dangerous and not advised. That can cause damage to the circuit or even a fire in the case of the copper wire. You have a dead short in the circuit. A power wire or fixture has developed a direct connection with ground. I came acrros one 94 Sedan Dville that had the wiring harnesses dry rotted under the hood and had to isolate and recoat individual wires. Luckily it was only a few or the harness would have been replaced. Look for damage in the trunk/undercariage to the rear harness to the rear lights.

That's insane. You have a fuse for a reason. DO NOT but anything beside the fuse that belongs there. You have a short circuit in the the system and it has to be found. I suggest you get some help from an electrical shop before you do some serious damage to that car.

you need to find the damaged harness not start a fire.there is a connecter behind the l/r trunk panel or carpet.that has all the wires for the rearend.unplug it and try installing a fuse.if stops blowing the short is in the rearend.if it keeps blowing unplug the turn signal switch and see if it blows.ty for using 2carpros

That's what I said. Should have made the rear fuse block as a isolation point clearer (thnx Cadieman).
