* Underhood Fuse Box: This is the larger fuse box and is located under the hood, usually near the battery. It protects the higher amperage circuits.
* Passenger Compartment Fuse Panel: This smaller fuse box is typically located inside the vehicle, often under the dashboard on the driver's side or passenger's side (check your owner's manual for the exact location on your specific model). This one protects the lower amperage circuits for interior components.
To find the exact location, consult your 2000 GMC Sierra owner's manual. The manual will have diagrams showing the location of both fuse boxes and will list what each fuse controls. This is the most reliable way to locate them.
