Check the glove compartment panel first, as it contains the main set of circuit protectors for interior systems such as lighting, audio, and climate control. Release the retaining clips, lower the cover, and use the printed chart inside to match each slot with its assigned component before removing anything.
The rear trunk section houses high-amperage links that support power distribution for the battery, rear electronics, and charging circuits. Access requires lifting the floor panel and removing the right-side trim. Always disconnect the negative battery terminal before touching these high-load elements to avoid short circuits or module damage.
Each slot is marked with a number and rated in amps, typically ranging from 5A to 80A. Use only identical ratings during replacement, as installing a higher value can lead to wiring overheating, while a lower value may cause repeated failure under normal load. A small plastic puller is usually stored in the panel for safe removal.
Common faults include blown protectors for power windows, central locking, or infotainment resets. Inspect the metal strip inside each unit; a visible break indicates failure. If multiple components stop working at once, trace shared circuits using the assignment chart rather than replacing parts randomly.

Open the glove compartment and inspect the main power distribution panel, as it contains the majority of low-amperage circuit protectors tied to interior systems. The label card inside the cover maps each slot to functions such as radio, interior lights, and seat controls.
Use the numbering sequence printed next to each slot to match circuits accurately. Do not rely on visual position alone, since layout variations may exist depending on installed options like navigation or premium audio modules.
In the trunk area, locate the secondary panel on the right side beneath the trim. This section holds high-current links for battery supply, rear electronics, and charging lines. Remove the plastic cover carefully to avoid damaging retaining clips.
Always disconnect the battery ground cable before working in the rear compartment, especially when handling high-load elements rated above 40 amps. This reduces risk of short circuits and protects control units.
Interior Panel Circuit Assignments
Typical assignments include 5A–15A slots for lighting, 20A for power outlets, and 30A for seat adjustment motors. Check the chart to confirm exact allocation, as shared circuits may feed multiple components like climate control and blower modules.
If a specific system fails, trace its assigned slot using the chart and verify continuity of the metal strip inside the protector. A broken strip indicates failure and requires replacement with the same rating.
Rear Compartment High-Load Distribution
Rear-mounted elements often range from 40A to 80A and supply modules such as the rear window defroster and power distribution unit. These components are larger and may be bolted rather than clipped in place.
After replacement, recheck system operation and monitor for repeated failure. Recurrent issues often point to wiring faults or overloaded circuits rather than a defective protective element.

Open the glove compartment and press the two side tabs inward to release the internal panel, then fold it down to reveal the primary electrical block. The layout card is fixed on the back side, allowing quick identification of each slot without removing additional trim.
Move to the trunk and lift the floor cover, then remove the right-side lining panel secured with plastic fasteners. Behind it sits the secondary power distribution section with larger current protectors and relay units. Use a trim tool instead of a screwdriver to avoid damaging clips or interior panels during removal.
Under the hood, locate a smaller housing near the passenger side firewall that contains additional relays and protection elements linked to engine management and cooling systems. Ensure the ignition is off and the key is removed before opening this compartment to prevent accidental activation of electrical components.
