Locate the interior and engine compartment electrical units and match each slot with the printed layout on the cover to identify circuits tied to lighting, control modules, and accessory systems.
Check amperage markings on each blade component before removal, commonly 5A, 10A, 15A, 20A, and 30A. Installing a higher value can overheat wiring and damage connected electronics.
Use the slot numbering molded into the housing to align positions with system labels such as BCM, HVAC, radio, and ignition circuits. This mapping allows precise tracing of current flow without removing additional parts.
Remove each component with a plastic puller and inspect the internal metal strip for breaks or discoloration. A damaged strip confirms a failed circuit link.
After reinstalling, press each piece firmly into place and test affected systems immediately. Repeated failure indicates issues in relays, wiring harnesses, or connected modules rather than the protective element itself.

Match each slot in the interior and engine compartment electrical units with the numbering molded into the housing and the layout printed on the cover to identify circuits such as BCM, ignition, lighting, and accessory lines.
Verify amperage ratings on each blade component before removal, typically ranging from 5A to 30A, and replace only with the same value. Use label abbreviations like ACC, IGN, BCM, and HVAC to trace current paths from the battery through relays to connected systems; after reinstalling, test each function immediately to confirm correct identification and stable operation.

Open the driver side door and remove the side cover on the dashboard end to access the interior electrical unit positioned behind a plastic trim piece.
The cabin unit is mounted laterally on the left side of the dashboard and contains multiple rows of blade-type components and relays. Key access points include:
- Driver side dashboard end cover
- Lower footwell trim area for extended access
- Side-mounted housing aligned with steering column
Use a plastic tool to remove the cover without damaging clips and check the printed layout inside for slot identification.
Lift the hood and locate the engine compartment power distribution unit near the battery on the driver side; it is enclosed in a sealed black housing with a snap-on lid that includes circuit labeling aligned with internal slot positions.
