2005 Chevrolet Blazer Service and Repair Manual

This factory service and repair manual for the 2005 Chevrolet Blazer documents the truck in Base, Xtreme and ZR2 form, in two-door and four-door sport utility bodies, with one engine throughout: the 4.3-liter overhead-valve V6 of 262 cubic inches, naturally aspirated, burning gasoline. Nothing about the drivetrain changes from one badge to another, so a technician can move from a specification table to a torque figure to a wiring diagram without first working out which version of the truck is on the hoist.

Known issues on the 2005 Blazer. Owners filed 15 complaints against this model year — a small number, and weighted toward the fuel system with 5, the electrical system with 4 and exterior lighting with 1. Those are all documented territory here: fuel pressure and delivery testing with the pump and injector specifications behind it, power distribution, grounds and circuit diagrams for the body, and the lamp, switch and connector detail that turns a lighting fault into a specific test rather than a parts swap.
