* Underhood Fuse Box: This is typically located on the driver's side fender well, near the battery. It's a larger box and houses higher amperage fuses.
* Interior Fuse Panel: This is usually found under the dashboard, on the driver's side. It's often located near the steering column, sometimes under a cover.
To be absolutely certain, consult your 2001 Chevy Silverado's owner's manual. The manual will have diagrams showing the exact locations of both fuse boxes and what each fuse controls.
