In this article we take a look at the first generation Chevrolet Silverado, produced from 1999 to 2007. Here you can find the Chevrolet Silverado 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006 and 2007 fuse box outline, get information about the location of the fuse boxes inside the vehicle and learn about the allocation of each fuse (fuse layout) and relay.
In the Chevrolet Silverado, the fuses for the cigar lighter/socket are located in the engine compartment fuse box (see “AUX PWR” and “CIGAR” / “CIG LTR” fuses).
