Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is turned off and keys are removed from the ignition.
Safety gloves and goggles are recommended to protect against electrical hazards.

2. Locate the Fuse Boxes

Cabin Fuse Box: Open the driver's side door and remove the cover from the fuse box located on the left side of the dashboard.
Under-Hood Fuse Box: Open the hood and locate the fuse box near the battery. Remove the cover carefully.

3. Check the Fuses

Visual Inspection:
- Examine each fuse in both fuse boxes.
- Look for broken filaments or melted plastic.
Continuity Test:
- Set the multimeter to the continuity setting.
- Touch the probes to both ends of the fuse.
- A beep or reading on the multimeter indicates the fuse is good; no beep means it is blown.

4. Replace Blown Fuses

Remove the blown fuse using fuse pullers or needle-nose pliers.
Insert a new fuse of the same amperage rating into the slot.
Ensure that the new fuse is seated properly.

5. Reassemble and Test

Replace the covers on both fuse boxes.
Start the vehicle and test the previously malfunctioning electrical components.
