Twisting could force the terminals open too far, resulting in a bad connection.

If an electrical component fails, always check the fuse first.

Always turn off all electrical components and the ignition switch before replacing a fuse. Never bypass a fuse with pieces of metal or foil.

The amperage value of each fuse is molded into the fuse body.

The fuse block is located below the left side of the dash. Later models have two fuse blocks - one for standard fuses located under the instrument panel on the left side of the dashboard and one for high current fuses in the engine compartment, adjacent to the battery.

In earlier models, the fuses are tubular glass body types, while in later models, miniaturized fuses with blade terminal design are employed.

All models covered in this manual have four fuse blocks.

Two types of fuses are used, depending on the date of manufacture. Early models use a glass tube design, while later models use miniaturized fuses with a blade terminal design.

If power is present on one side of the fuse but not the other, the fuse is blown.

In earlier models, the fuses are tubular glass body types, while in later models, miniaturized fuses with blade terminal design are employed.

Each electrical circuit needs a specific amount of protection, and the amperage value of each fuse is usually molded into the fuse body.

To replace a fuse, first turn the ignition switch OFF. Grasp the push-in type fuse with the provided tool, or a pair of needle-nose pliers. Look through the side of the fuse body to determine if the fuse element is blown. Check the amperage rating of the fuse which was removed and obtain a new fuse of the same rating. Align the fuse with its mounting position and push it into place until fully seated in the panel. Turn the ignition switch on and operate the accessory that was protected by that fuse.

The best way to check a fuse is with a test light. Check for power at the exposed terminal tips of each fuse.

Miniaturized fuses are used because their compact dimensions and convenient blade-type terminal design allow fingertip removal and installation.

The fourth fuse block is located next to the battery and contains the primary battery fuses.
