Check the driver side dashboard cover first to access the interior electrical block, as most low and mid-current circuits for lighting, infotainment, and controls are routed through this area. Remove the side trim to reveal the slot map printed on the cover.
Match each slot number with its circuit label and verify the amperage rating stamped on top, typically ranging from 5A to 20A for interior systems and higher values in the engine compartment for heavy loads.
Use a multimeter on exposed metal contacts to confirm continuity without removing components, which helps detect internal breaks that are not visible through the plastic housing.
The engine compartment distribution unit contains larger cartridge-style elements and relays for systems such as cooling fans, ABS, and engine control modules. Use the legend inside the cover to identify each position before testing or replacement.

Locate the interior electrical block on the driver side dashboard and use the printed slot map on the cover to identify circuits before removing any component.
Match each position with its labeled system, such as lighting, infotainment, or climate control, and confirm the amperage rating marked on top, typically between 5A and 20A for cabin circuits.
Engine compartment distribution units contain higher-rated links and relays for systems like cooling fans, ABS, and engine management, with cartridge-style components handling heavier electrical loads.
Test continuity using exposed contact points with a multimeter to detect internal breaks, and replace only with identical ratings and sizes to maintain proper circuit protection.
Driver side fuse panel location and slot assignment for interior systems
Open the driver door and remove the side dashboard cover to reach the interior electrical block; the slot index printed on the back of this cover shows circuit names and positions.
Use the layout chart to match each slot with its system before testing or replacement, focusing on labeled rows tied to cabin electronics.
- RADIO supports infotainment unit and speakers
- CLUSTER or METER controls instrument display and warning lights
- AC or HVAC powers climate control modules and blower system
- PWR OUTLET connects to accessory sockets and charging ports
Amperage values indicate load capacity, with 5A used for sensors and control lines, 10A for electronics, and 15A for components with moving parts.
Use a test light or multimeter on exposed terminals to verify current flow without removing the component.
If multiple systems fail, inspect shared circuits such as accessory or ignition-switched lines, as they distribute power across several devices.
Install replacements with identical ratings and size to maintain stable operation and prevent wiring damage.
