Check the interior panel under the dashboard on the driver’s side first, as most cabin circuits like infotainment, lighting, and accessory outlets are routed through this section. Use the printed label to match each slot with its assigned circuit before removing any protective insert.
Open the hood and locate the main power distribution center near the battery, where high-current links control systems such as cooling fan, ignition, and braking modules. Verify amperage ratings on each element to avoid wiring damage or repeated electrical faults.
Remove the suspected component and inspect the internal metal strip for breaks or burn marks. Use a multimeter to confirm continuity, since some failures are not visible through the plastic housing and may cause intermittent issues.
Follow the numbering and labels molded into the panel housing to trace circuits like power windows, HVAC, and instrument cluster. Keep spare inserts with common ratings such as 10A, 15A, and 20A available for quick troubleshooting and replacement.

Locate the interior panel under the driver-side dashboard and the engine bay power distribution center near the battery, then match each slot with its labeled circuit before removing any protective insert.
Focus on key systems such as infotainment, lighting, power outlets in the cabin, and high-load components like cooling fan, ABS, and ignition modules in the engine compartment, verifying each position using the printed legend and molded numbering.
Use a multimeter to check continuity and confirm failures, and replace elements only with identical amperage ratings such as 10A, 15A, 20A, or higher where required to prevent overheating, wiring damage, or repeated electrical faults.
Interior fuse panel location and assignment for cabin electronics
Remove the lower dashboard cover on the driver’s side to access the interior electrical panel, then use the printed legend to match each slot with systems like infotainment, interior lighting, and accessory outlets before removing any insert.
Identify circuits using labels such as ACC, RADIO, and BCM, which control most cabin electronics, and follow the numbering molded into the panel housing to avoid selecting the wrong position.
Check amperage values stamped on each insert, typically ranging from 5A to 20A, and replace only with identical ratings to prevent overheating or unstable operation of interior components.
Test suspected elements with a multimeter to confirm continuity, and inspect shared lines like ACC or IGN if multiple cabin systems fail simultaneously, as these often distribute power across several modules.
