* Under the hood: This is the most common location for the main fuse block and contains larger fuses. Look near the battery, usually on the driver's side fender.
* Inside the cab: A smaller fuse panel, often called the "interior fuse panel," is generally located under the dashboard, either on the driver's side or the passenger's side. This one usually has smaller fuses and protects interior components.
To be absolutely certain, consult your owner's manual. It will have a diagram showing the exact location and what each fuse protects. You can also often find a diagram inside the fuse panel covers themselves.
If you don't have the owner's manual, you can try searching online for a 1993 Chevy truck [your specific model] fuse box diagram. Many websites and forums dedicated to Chevy trucks will have this information.
