Relay and fuse block

DESCRIPTION

Fig. 4 Relay and Fuse Block Location

1 - JUNCTION BLOCK

2 - RELAY AND FUSE BLOCK

The relay and fuse block is snap fit onto mounting tabs located on the end of the Junction Block (JB) nearest to the dash panel, under the left outboard end of the instrument panel (Fig. 4). The relay and fuse block provides additional capacity for distribution and control of electrical current for some of the accessory systems that are unique to this vehicle, and which could not be accommodated by the JB or the Power Distribution Center (PDC). The relay and fuse block has cavities for up to four additional blade-type mini fuses, the electronic combination flasher, and three additional International Standards Organization relays (one standard-type and two micro-type).

The relay and fuse block components are accessed for service by removing the steering column opening cover from the instrument panel. The relay and fuse block is then disengaged from the JB mounting tabs and pulled out from under the instrument panel. Service replacement of the relay and fuse block unit requires instrument panel assembly removal.

The relay and fuse block unit cannot be repaired and is only serviced as a unit with the instrument panel wire harness assembly. If the relay and fuse block housing or its internal circuits are faulty or damaged, the entire instrument panel wire harness unit must be replaced.

OPERATION

The relay and fuse block is integral to the instrument panel wire harness, and all circuits entering or leaving this module do so through the instrument panel wire harness. Internal connection of all of the relay and fuse block circuits is accomplished by hard wiring. Refer to Fuse/Fuse Block in the index of this service manual for the location of complete circuit diagrams and cavity assignments for the relay and fuse block.
