The Silverado typically has two fuse boxes: an engine-compartment Power Distribution Center on the driver’s side of the engine bay, and an interior fuse panel under the driver’s dash. Exact locations can vary by model year, so check the diagram on the covers or the owner's manual for your truck.
Locations of the fuse boxes
To locate the fuses quickly, note that GM trucks generally keep a large under-hood block for main power and a smaller panel inside the cab for accessories and lighting. The following sections outline where to look on most model years.
Engine compartment fuse box (Power Distribution Center)
Look for a large black plastic box in the engine bay on the driver’s side. The cover is labeled with a diagram of circuits and fuse amperages. Access is gained by unclipping or hinged removal of the cover. The block typically houses fuses and relays for major systems such as the engine, fuel, charging, and ABS.
- Location: generally on the driver’s side of the engine bay, near the firewall or fender, depending on year.
- Identification: a sturdy black plastic housing with a removable cover labeled “FUSES” or “Power Distribution Center.”
- What’s inside: a bank of fuses and relays for high-demand systems.
Always confirm the circuit map on the cover and use the same amperage when replacing fuses. If in doubt, consult the owner’s manual or a dealer service department.
Interior fuse box (cab fuse panel)
The second fuse box is inside the cabin, typically on the driver’s side under the dashboard. In some generations it sits behind a knee bolster, in others behind a small access panel or inside the glove compartment. The fuse map is usually printed on the inside of the panel cover or found in the manual.
- Location: under the driver's side dash; sometimes behind a panel or near the knee area.
- Identification: a smaller panel with a detachable cover labeled with circuit names and amperages.
- What’s inside: fuses for interior electronics, lighting, power accessories, and some auxiliary systems depending on year.
When replacing fuses, select the correct amperage and ensure the problem isn’t caused by a short or faulty component. If the fuse repeatedly blows, seek professional diagnostic help.
How to read the fuse diagrams and stay safe
Fuse diagrams live on the inside of each panel’s cover. For newer Silverado models you may also find a QR code linking to a digital map. For any work near the battery or under-hood components, disconnect the battery to avoid arcing and consult a professional if you’re unsure.
Reading the diagrams helps you target the right fuse quickly and avoid guesswork. Always replace with the same amperage rating and secure the panel cover properly before starting the vehicle.
Summary
Chevrolet Silverado fuse boxes are typically located in two places: the engine compartment (Power Distribution Center) and the interior cab fuse panel on the driver’s side. Exact placements and the fuse map vary by model year, so consult the cover diagrams and the owner's manual for your specific truck. Proper fusing and careful replacement can save time and prevent electrical issues on the road.
