* Under the hood: This is the most common location. Look on the driver's side, usually near the battery. It's often a black plastic box.
* Under the dash: Less common, but possible. If it's not under the hood, look on the driver's side of the dashboard, usually towards the lower portion. You might need to remove a small access panel.
To be certain: Check your owner's manual. It will have a diagram showing the exact location and what each fuse controls. If you don't have the manual, you can often find a downloadable version online through a Chevy parts website or a site like Haynes Manuals.
