Where is the cigarette lighter fuse in 2003 Chevrolet trailblazer?
The cigarette lighter fuse location in a 2003 Chevrolet Trailblazer is in the underhood fuse block. It's *not* typically in the interior fuse panel. You'll need to consult your owner's manual for the exact fuse number and its location within that underhood block. The manual will have a diagram showing the fuse layout.
