Check the interior power distribution unit under the dashboard on the passenger side before troubleshooting any electrical fault. This area controls cabin systems such as radio, interior lights, power outlets, and dashboard electronics. Each slot is marked with amperage values like 10A, 15A, and 20A, which must be matched exactly during replacement.
The engine compartment unit near the battery supplies high-current components including cooling fans, ignition system, and ABS. Inspect this section first if the vehicle fails to start or major systems stop working. Relay switches in this area manage power flow and can be tested by swapping with identical units.
Use a multimeter to verify continuity across each protective element instead of relying only on visual checks. Disconnect the negative battery terminal before removal to avoid short circuits, control module faults, or wiring damage.

Check the passenger-side interior distribution block behind the lower dash trim to diagnose issues with cabin electronics such as radio, interior lighting, power outlets, and instrument cluster. Each slot is labeled with a number and amperage rating, typically 10A, 15A, or 20A, and must match the replacement part exactly to avoid circuit damage.
Inspect the engine compartment power distribution unit near the battery for systems related to starting, cooling, and safety modules, including the fuel pump, ABS, and radiator fan. High-current circuits use larger rated inserts and relays that control switching; swap identical relays from non-critical circuits to test functionality. Use a multimeter to confirm continuity across each element and check terminals for corrosion or looseness to maintain stable electrical contact.
Interior fuse panel location and slot mapping for cabin electrical systems
Remove the passenger-side lower dash cover to access the interior electrical distribution unit positioned behind the trim panel.
Use the printed layout on the cover to match numbered slots with protected systems such as radio, dome lights, dashboard cluster, and power outlets.
Follow the correct orientation by reading rows horizontally from top to bottom to avoid selecting the wrong slot.
- 10A position – instrument cluster and warning indicators
- 15A position – audio system and accessory outlet
- 20A position – windshield wipers and washer motor
- 25A position – power windows and door locks
Pull each element using the plastic extractor stored inside the cover to prevent bending contacts.
Check continuity with a multimeter by placing probes on both terminals; a continuous reading confirms a working component.
Inspect terminals for discoloration or looseness, which may indicate overheating or poor contact.
Install replacements with identical amperage ratings and keep spare inserts in designated slots for quick access during electrical troubleshooting.
