Check the interior and engine bay power panels first when any electrical component stops working, as both areas contain separate groups of circuit protection links and relays. The cabin panel is usually behind a side cover on the dashboard, while the under-hood unit sits near the battery.
Each slot corresponds to a specific system such as lighting, infotainment, ABS, or climate control. The amperage rating printed on each link ranges from 5A to 40A, depending on load requirements. Matching these values correctly prevents overheating and wiring damage.
Use a test light or multimeter to confirm voltage presence before removing any component. A working link should show power on both sides; a break inside indicates failure. Relays in adjacent positions control switching for high-load systems like cooling fans and fuel delivery.
Keep the layout chart from the panel cover visible during inspection, as it maps each numbered position to its function. This reduces guesswork and avoids pulling unrelated parts that may still be operational.

Match each numbered slot with the layout chart under the panel cover before removing anything, as multiple circuits share similar ratings and positions across the cabin and engine compartment units.
Interior panel circuits typically handle lighting, infotainment, and comfort systems, with ratings from 5A to 30A. Higher loads such as blower motor or heated seats are placed in reinforced slots with thicker terminals to handle sustained current.
Engine Compartment Power Distribution
Under-hood layout includes high-current links for cooling fans, ABS pump, and battery feed lines. These components often use 30A to 60A strips and are paired with relays that control switching. A failed relay may mimic a broken link, so test both before replacement.
Check continuity using a multimeter by probing both terminals of each link while it remains installed; a voltage drop across the element indicates internal damage. Remove only confirmed faulty parts to avoid disturbing stable connections.
Relay Identification and Swapping
Relays are grouped by function and share identical housings, allowing temporary swapping for diagnostics. Move a relay from a non-critical circuit to test suspected failure, then reinstall it to its original position after verification.
Interior and Engine Bay Fuse Panel Locations and Access Instructions
Remove the dashboard side cover on the driver side to reach the interior electrical panel; it snaps off without screws and reveals rows of small blade links arranged by circuit group.
- Open the driver door fully
- Insert fingers into the side slot of the trim cover
- Pull outward until clips release
- Locate the panel directly behind the cover
The cabin unit handles low to medium load systems such as lighting, infotainment, and climate controls. Each row is numbered, and a printed chart on the cover maps positions to functions.
Access the under-hood distribution unit near the battery for high-current circuits like cooling fans and ABS.
- Lift the hood and secure it
- Find the rectangular plastic housing beside the battery
- Press the locking tabs on both sides
- Lift the cover straight up
This unit contains larger strip-style links and relays designed for higher loads. Keep the cover nearby during service, as it includes the layout reference needed for correct identification.
After inspection or replacement, press both covers firmly back into place until all clips engage, ensuring protection against moisture and dirt.
