Fuse Block: Description and Operation

FUSE BLOCK
An electrical Fuse Block is located under the left side of the instrument panel. It serves to simplify and centralize numerous electrical components, as well as to distribute electrical current to many of the accessory systems in the vehicle.

The fuse block houses blade-type fuses, a Time Delay Relay, and the Turn Signal/Hazard Flasher. Internal connection of all the fuse block circuits is accomplished by an intricate network of hard wiring and bus bars.

The fuses, relays, and flashers are available for service replacement. The fuse block unit cannot be repaired and is only serviced as an assembly. If any circuit or the fuse block housing is faulty or damaged, the entire fuse block and instrument panel wire harness assembly must be replaced.

FUSE/RELAY BLOCK
A Fuse/Relay block is located in the trunk and is used to provide current distribution to several electrical components. The Fuse/Relay Block has molded plastic housing that is located in the left side of the trunk. The Fuse/Relay Block has a molded plastic cover that includes an integral hinge and latch. The Fuse/Relay Block cover is easily removed for service access and has a convenient fuse and relay chart affixed to the inside surface of the cover to ensure proper component identification. The Fuse/Relay Block housing is attached to and is part of the audio amplifier mounting bracket assembly. The Fuse/Relay Block outputs are routed through the uni-body wiring harness.

A wire from the battery to the Fuse/Relay Block is used to supply current to several fuses and timer/relays located in the Fuse/Relay Block. The Fuse/Relay Block includes up to four fused and up to two timer/relays. There is one cartridge fuse, one circuit breaker, two blade type fuses, one timer/relay, and ISO one relay. Internal connection of the Fuse/Relay

Block circuits is accomplished by a network of hardwired connections. The fuse cartridges, timer relays, and fuses are available for service replacement. The Fuse/Relay Block unit cannot be repaired and is only serviced as a unit with the uni-body wire harness. If the Fuse/Relay Block is faulty or damaged, the unibody wire harness assembly must be replaced.

NOTE: If the unibody harness with the Fuse/Relay Block is being replaced with a new unit, be certain to transfer each of the fuses and relays from the old fuse/relay block to the proper cavities of the new fuse/relay block for proper power distribution. Refer to the fuse/relay block for the proper cavity assignments.
