Power Distribution Box

See Figures 14 through 18

The power distribution box (also known as the main fuse box) is mounted in the following locations:



Navajo models: in the engine compartment on the right inner fender, next to the starter relay
 
MPV models: in the engine compartment on the right fender liner.
 
Pickup models: in the engine compartment on the right fender apron just behind the battery on the B2200, or, on the left fender apron on B2600 models.
 

The power distribution box houses the fuses and relays for most of the under hood components which are not controlled by a dash mounted switch (such as the alternator, fuel pump, ECM, etc.). The fuses and relays are replaced in the same manner as the fuse panel inside the vehicle. The power distribution box cover is hinged on one end and utilizes a retaining latch on the other. Simply release the latch and lift the cover up to gain access to the fuses and relays.
