Solution

1. Preparation

Gather the necessary tools: multimeter, screwdriver (if required), and replacement fuses.
Ensure the vehicle is turned off, and the key is removed from the ignition.

2. Locate the Fuse Boxes

Interior Fuse Box: Open the driver’s side door and remove the cover panel on the left side of the dashboard.
Engine Compartment Fuse Box: Open the hood and locate the fuse box near the battery.

3. Inspect the Fuses

Remove the fuse box cover and locate the fuses based on the diagram in the owner’s manual.
Pull out each fuse one at a time using fuse pullers or pliers.
Check each fuse visually for a broken filament or discoloration.

4. Test with Multimeter

Set the multimeter to the continuity setting.
Place one probe on each end of the fuse terminals.
If the multimeter beeps or shows a reading indicating continuity, the fuse is good; if not, it is blown and needs replacement.

5. Replace Faulty Fuses

Obtain replacement fuses that match the amperage rating of the blown fuses.
Insert the new fuse into the same slot, ensuring it is seated properly.
Replace the fuse box cover and ensure it is secure.
