Miniaturized fuses are employed in the fuse block. These compact fuses, with blade terminal design, allow fingertip removal and replacement. To check the fuses, turn the ignition key to the On position and, using a test light, probe each exposed terminal of each fuse. If the test light glows on both terminals of a fuse, the fuse is good. If power is available on one side of the fuse but not the other, the fuse is blown. A blown fuse can be easily identified through the clear plastic body by visually inspecting the element for evidence of damage.

If the replacement fuse immediately fails, don't replace it again until the cause of the problem is isolated and corrected. In most cases, this will be a short circuit in the wiring caused by a broken or deteriorated wire.
