Check the power distribution layout under the hood first, since most electrical faults trace back to that module rather than the interior panel. Locate the main power center near the battery and compare each slot number with its assigned circuit before replacing any component.
Each slot is rated with a specific amperage, typically ranging from 10A to 40A, and using a higher rating can damage wiring or connected systems. Match the color-coded element exactly and inspect the metal strip inside for breaks or burn marks before deciding it has failed.
The cabin panel, positioned behind the glove compartment, controls smaller circuits such as interior lighting, radio, and accessory ports. Access requires releasing the side stops of the glove compartment and lowering it fully to expose the panel cover.
Relays in the power center control systems like the fuel pump, cooling fan, and starter. If a system stops working intermittently, swap the relay with another identical unit in the same panel to test functionality without new parts.
Always disconnect the negative battery terminal before working with any electrical distribution unit. This prevents short circuits and protects onboard modules from voltage spikes during inspection or replacement.

Use the power distribution center under the hood as the primary reference point, since it contains high-current links for systems like the alternator, ABS, and radiator fan. Each slot is numbered and tied to a specific circuit; for example, positions in the 20–30A range often support cooling and ignition components, while 40A slots handle blower motor and main power feeds. Cross-check the lid label with the slot grid to avoid incorrect replacements.
The interior panel behind the glove compartment handles low-amperage circuits, typically 10A–25A, assigned to lighting, infotainment, and auxiliary outlets. Relays grouped in the engine compartment control switching for fuel delivery and starter engagement; identical relay units can be temporarily swapped to confirm faults. Always verify amperage markings and inspect terminals for corrosion or looseness before reinstalling any component.
Where to Find Fuse Boxes in 2013 Jeep JK and How to Access Them
Open the hood and locate the main power distribution unit next to the battery, as this is where high-load circuits are grouped. The cover is secured with plastic clips; press and lift them to remove it. Inside, a printed layout shows slot numbers and assigned systems. This area handles components like cooling fans, ignition, and braking electronics, so inspect it first when multiple systems fail at once.
Access the interior panel by lowering the glove compartment fully. Press inward on both side stops to release it, allowing the compartment to drop down and reveal the panel behind it. This section manages smaller circuits tied to cabin electronics and accessories.
Key locations to check
- Engine bay near battery for high-current links and relays
- Behind glove compartment for interior circuits
- Panel cover labels for quick slot identification
Before opening any panel, disconnect the negative battery terminal to prevent short circuits. After gaining access, use a puller tool stored inside the cover to remove elements safely without damaging contacts.
Access tips
- Work in good lighting to read slot markings clearly
- Keep removed parts organized to avoid mix-ups
- Reinstall covers tightly to protect against moisture and dust
