Chevrolet Silverado 2nd generation was produced in 2007, 2008, 2009, 2010, 2011, 2012 and 2013. In this post we will present a description of fuses and relays Chevrolet Silverado with fuse box diagrams, their locations and photo examples of performance. Let’s highlight the fuse responsible for the cigarette lighter.
The fuse and relay assignment may vary from that shown and depends on the year of manufacture and the level of electrical equipment in your vehicle.
Passenger compartment fuse box
In the passenger compartment, the fuse box is located in the left-hand end of the instrument panel behind the protective cover.
