The 1st generation Chevrolet TrailBlazer was produced in 2001, 2002, 2003, 2004, 2004, 2005, 2005, 2006, 2007, 2008, 2009, 2010 with the GMT360 designation. During this time, the model received an update. In this article you can find a description of fuses and relays Chevrolet Trailblazer 1 with fuse box diagrams, their locations and photo examples of performance. Let’s highlight the cigarette lighter fuse.
The fuse and relay assignment may differ from the one shown and depends on the year of manufacture and the level of electrical equipment of your vehicle.
Engine compartmen
In the engine compartment, under the bonnet, the fuse and relay box is mounted on the left-hand side next to the battery.
