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

If the replacement fuse immediately fails, it is recommended not to 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.

The best way to check the fuses is with a test light. Check for power at the exposed terminal tips of each fuse. If power is present at one side of the fuse but not the other, the fuse is blown. A blown fuse can also be identified by visually inspecting it, as the element between the terminals melts.

There are two fuse panels; one is in the power distribution box in the engine compartment, and the other is above the driver's footwell.

If a continuity check is called for, the blade terminal tips are exposed in the fuse body, allowing easy removal and replacement.

The electrical circuits of the vehicle are protected by a combination of fuses, circuit breakers, and cartridge-type fusible links.

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.

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

The amperage value of each fuse is 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 underhood power center is located next to the battery in the engine compartment and contains relays and high-amperage fuses.

If the replacement fuse immediately fails, don't replace it again until the cause of the problem is isolated and corrected, as it is often due to a short circuit in the wiring caused by a broken or deteriorated wire.

Fusible links appear to be a heavier gauge due to the thick insulation, but they are actually several wire gauges smaller than the wire they are designed to protect.
