The all-new Blazer was introduced in 1994 as a 1995 model. The SUV won the Motor Trend 1995 Truck of the Year award. In this article, we will take a detailed look at the fuse box diagrams of the Chevrolet Blazer (S-10) 
1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005  , as well as the GMC S-15 Jimmy and Envoy (1998-2000).
