Cadillac 12065931 Fuse,Maxi 20 A Yellow (Autofuse Blade Type)

Electrical circuits are protected by a combination of fuses and circuit breakers. Models covered have a fuse/relay panel in the engine compartment, as well as an electrical center or fuse/relay panel under the rear seat or in the trunk. A large underhood fuse/relay panel is located in the engine compartment on all models. Most models have a fuse block or an electrical center like this mounted under the rear seat or in the trunk. Each of the fuses is designed to protect a specific circuit, and the various circuits are identified on the fuse panel cover or the fuse panel itself. Miniaturized fuses are employed in the fuse block. These compact fuses, with blade terminal design, allow fingertip removal and replacement. If an electrical component fails, always check the fuse first. The easiest way to check fuses is with a test light. Check for power at the exposed terminal tips of each fuse. If power is present on one side of the fuse but not the other, the fuse is blown. When removed, a blown fuse is easily identified through the clear plastic body. Visually inspect the element for evidence of damage. When a fuse blows, the element between the terminals melts. Be sure to replace blown fuses with the correct type. Fuses of different ratings are physically interchangeable, but only fuses of the proper rating should be used. Replacing a fuse with one of a higher or lower value than specified is not recommended. Each electrical circuit needs a specific amount of protection. The amperage value of each fuse is molded into the fuse body. If the replacement fuse immediately fails, don't replace it again until the cause of the problem is isolated and corrected. In most cases, the cause will be a short circuit in the wiring caused by a broken or deteriorated wire.

If a replacement fusible link blows again, troubleshooting the circuit is necessary before installing another link.

The under hood fuse/relay panel is located in the right-front corner of the engine compartment.

There are different sizes of fuses, including small, medium, and large, all with the same blade terminal design. The medium and large fuses can be removed by hand, but the small fuses require pliers or a fuse-puller tool.

A blown fuse can be identified if power is present on one side but not the other, or through visual inspection, as the element between the terminals melts when it blows.
