Quick answer
The 2017 Chevrolet Suburban has three main fuse box locations:
- Underhood Fuse Block: Located in the engine compartment on the driver's side.
- Instrument Panel (Dash) Fuse Block: Located in the passenger footwell, behind a panel on the side of the center console.
- Rear Cargo Area Fuse Block: Located in the rear cargo area on the driver's side, behind a trim panel.
Underhood Fuse Block
The underhood fuse block contains high-current fuses and relays for critical engine and vehicle systems. Always disconnect the negative battery terminal before servicing fuses or relays in this box.
Relays: The underhood fuse block also houses various relays for components such as the starter, fuel pump, and air conditioning compressor. Refer to the fuse box lid diagram for specific relay locations.

Before you pull a fuse on the 2017 Chevrolet Suburban
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
