Check the interior panel on the driver side dashboard first when power windows, audio system, or dashboard lights stop working, as most cabin circuits pass through this distribution point.
This panel is usually located behind a small removable cover near the steering column. Each slot is labeled with an amperage value such as 10A, 15A, or 20A and connected to systems like air conditioning, lighting, and onboard electronics. Use the exact same rating when replacing a blown element to prevent overheating or repeated failure.
Under the hood, a second power distribution unit handles higher current systems including cooling fans, ignition supply, and ABS. Inspect both interior and engine compartment panels during troubleshooting, since faults can originate from either section.
Test each circuit with a multimeter or test light to confirm voltage flow rather than relying only on visual inspection. A damaged insert may show a broken internal strip or discoloration, while repeated failure often points to wiring damage or a malfunctioning component connected to that line.

Match each slot to its labeled circuit using the panel cover, since interior and engine compartment units separate low-current electronics from high-load systems.
The cabin distribution panel supplies power to systems such as dashboard lighting, audio unit, power windows, and climate control. Each position is marked with a rating, typically 10A to 30A, and linked to a specific circuit path. Follow conductor colors from each slot to trace connections toward switches and devices behind the dashboard.
Verify power flow using a multimeter by checking both sides of each protective insert, ensuring voltage enters and exits the slot without interruption.
In the engine compartment, the secondary distribution center manages higher current circuits including cooling fans, ABS, and ignition supply. Larger cartridge-style elements and relays are arranged in rows. Keep track of relay positions before removal to avoid incorrect placement.
Circuit tracing steps
Use a structured process to locate faults:
Check main power feed from battery, inspect each insert for continuity, follow conductor routing to the affected component, and confirm ground connections attached to the chassis.
Common circuit groups include lighting, HVAC system, infotainment, and safety electronics. Each group is isolated to prevent a single failure from disabling unrelated systems.
Inspect terminals for corrosion or looseness, since poor contact can cause intermittent issues such as flickering lights or unstable electronic behavior without a complete loss of power.

Open the driver side lower dashboard cover to access the main interior power distribution panel, positioned near the steering column above the footwell.
This cabin-mounted unit sits behind a small plastic lid that can be removed without tools. Inside, multiple rows of protective inserts are arranged with clear labels for systems like audio, lighting, and climate control. Use a flashlight to read markings clearly, as the mounting angle limits visibility.
Check the left side of the dashboard when the door is open, since some versions place the access panel on the side trim facing the driver seat.
Wiring harnesses extend from this location across the dashboard and down toward switches and control modules. Follow these harness paths to trace connections when diagnosing electrical issues.
Lift the hood and locate the engine compartment distribution unit near the battery, typically mounted along the inner fender in a sealed plastic housing.
This unit contains larger protective elements and relays responsible for high-current systems. Layout inside follows a grid pattern with clearly separated sections for relays and high-amperage inserts.
Use careful access steps when opening the housing:
- Release plastic clips without forcing them
- Lift the cover evenly to avoid cracking
- Note component positions before removal
- Keep debris away from exposed terminals
Use both interior and engine bay panels during troubleshooting, since cabin systems rely on the dashboard unit while cooling, charging, and ignition circuits depend on the under-hood distribution center.
