Check the interior power distribution unit under the driver-side dashboard first, as it controls most cabin systems such as lighting, radio, and accessory outlets. Remove the cover and use the printed layout to identify each slot and its assigned circuit.
The engine compartment electrical center near the battery handles high-load systems including ignition, cooling fans, and charging components. Use a multimeter or test light to verify continuity instead of relying only on visual inspection.
Each protective element is marked with an amperage rating, typically ranging from 10A to 50A depending on circuit demand. Always replace with the same value to prevent wiring damage or repeated failure.
If a circuit continues to fail after replacement, inspect related wiring, relays, and connectors for short circuits, corrosion, or loose contacts. Persistent issues usually indicate a fault outside the distribution unit.

Open the driver-side lower dash cover and align the printed layout with the mounted unit to identify each slot by number and amperage before removing any component.
- 10A–15A positions support interior lights, control modules, and instrument cluster
- 20A circuits supply radio, power outlets, and accessory systems
- 30A and higher ratings handle power windows, seats, and HVAC motors
- Engine bay distribution center includes high-load links for starter and alternator
Test each element using a multimeter in continuity mode, reinstall matching amperage values only, and verify relay positions near the engine compartment unit to ensure proper operation of connected systems.
Interior fuse panel location and detailed circuit assignment list
Remove the lower dash cover on the driver side to access the cabin electrical unit, then use the printed layout on the inside of the cover to match each slot with its assigned circuit and amperage rating.
Key circuit assignments
Lower-rated positions such as 10A and 15A handle interior lighting, instrument cluster, and control modules, while 20A slots supply radio and accessory outlets. Higher values around 25A–30A are used for power windows, seat controls, and climate system components.
Identification and handling
Align the cover correctly when reading the layout, remove components with a puller tool, and verify each one using a multimeter before reinstalling the same amperage value to maintain stable operation.
