Fuse Block: Description and Operation

Fig.1 Fuseblock Module Location:

An electrical fuseblock module is mounted on the dash panel in the passenger compartment of the vehicle (Fig. 1). The fuseblock module serves to distribute electrical current to many of the accessory systems in the vehicle. The fuseblock module houses up to twenty blade-type mini fuses.

The molded plastic fuseblock module housing has an integral mounting bracket that is secured with two screws to a bracket welded on the dash panel just above the heater and air conditioner housing. The glove box is rolled down from the instrument panel for service access of the fuseblock module fuses. An adhesive-backed fuse layout map is located on the heater and air conditioner housing below the fuseblock module to ensure proper fuse identification.

The fuseblock module is integral to the cross body wire harness. If any internal circuit or the fuseblock module housing is faulty or damaged, the entire fuseblock module and cross body harness unit must be replaced.

All of the circuits entering and leaving the fuse-block module do so through the cross body wire harness. Internal connection of all of the fuseblock module circuits is accomplished by an intricate combination of hard wiring and bus bars. Refer to Fusel Fuse Block for the location of complete fuseblock module circuit diagrams.
