Chevrolet TrailBlazer is an American five-door mid-size SUV. It was produced in 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008 and 2009, 2010. In this article, we will consider in detail the schemes of the first generation Chevrolet TrailBlazer (GMT360), as well as Buick Rainier (2004-2007); GMC Envoy (2002-2009); Saab 9-7X (2004-2009); Isuzu Ascender (2002-2008) and Oldsmobile Bravada (2002-2004).
Here you will find the locations and photos of the mounting blocks. We will separately note the fuses responsible for the cigarette lighter and fuel pump.
In the engine compartment
The underhood unit is located on the passenger side. It is covered with a plastic cover.
