* Full-size K5 Blazer: The fuse box is typically located under the hood, on the driver's side, near the battery.
* S-10 Blazer: The fuse box is typically located under the dash, on the driver's side. It's usually visible after removing a small access panel.
To be absolutely certain, consult your owner's manual. If you don't have the manual, you can often find a digital version online through sites like Helms, Inc. (a common source for GM repair manuals) or by searching for "[Year] Chevy Blazer Owner's Manual" on a search engine. A picture of the fuse box diagram is usually included in the manual.
