Check the glove compartment panel first when electrical components fail, as many circuits for lighting, infotainment, and control modules are grouped in this location behind a removable cover.
The trunk-mounted power distribution unit handles additional circuits including rear electronics and battery-related connections, with higher amperage links compared to the cabin area.
Use the printed layout chart placed near the panel or inside the cover to match each numbered slot with its assigned circuit, reducing the risk of removing the wrong component.
Test each protective element with a multimeter by checking voltage on both terminals; a break in continuity indicates failure and requires replacement with the same amperage rating.

Locate the correct panel using the layout chart before removing any component, as multiple distribution units are installed across the vehicle including glove compartment and trunk areas.
The glove compartment unit contains most cabin-related circuits such as infotainment, climate control, and lighting, with ratings typically ranging from 5A to 30A.
Rear-mounted distribution near the battery handles higher-load circuits and includes larger cartridge-style protective elements along with grouped relays.
- 5A–10A for sensors and control modules
- 15A–30A for lighting and accessory circuits
- 40A+ for power-intensive systems
Check voltage across both terminals using a multimeter before removal; a working element shows continuity, while a break interrupts current flow.
Relays positioned рядом control switching for systems like fuel delivery and cooling fans, and identical units can be swapped to verify faults.
If the same slot fails repeatedly, inspect wiring harnesses and connected devices for short circuits rather than replacing the protective element again.
Keep spare components and a puller tool available to handle sudden electrical issues without delay.
Exact Fuse Box Locations in Glove Compartment Trunk and Engine Bay
Open the glove compartment and press the side stops inward to fully drop it down, revealing the primary electrical block mounted behind a protective cover; use a plastic trim tool to avoid damaging clips while accessing it.
The luggage compartment unit sits on the right side behind a removable trim panel; pull the fabric or plastic cover gently, then release the retaining tabs to expose the secondary power distribution area connected to rear lighting and audio systems.
Under the hood, locate the main power distribution center near the right side of the engine bay close to the firewall; lift the locking tabs and remove the lid to access high-current links tied to starter, cooling fan, and control modules.
Follow this sequence for safe access:
- Turn off ignition and remove the key
- Disconnect the negative battery terminal if working on high-current lines
- Use pullers or insulated pliers for component removal
- Check amperage ratings before replacement
Verify placement using the legend printed on each cover, as layouts differ by trim level and equipment; mismatched ratings or incorrect slots may lead to system faults or non-working electronics.
