Solution

1. Preparation

Gather necessary tools:
- Fuse puller or needle-nose pliers
- Multimeter
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Access Fuse Box

Locate the fuse box by referring to the owner’s manual.
Open the fuse box cover carefully to avoid damaging any clips.

3. Inspect Fuses

Use a fuse puller or needle-nose pliers to remove each fuse one at a time.
Visually inspect each fuse for a broken filament or burn marks.
For further testing, set the multimeter to continuity mode and touch the probes to both ends of the fuse. A beep or a reading indicates the fuse is good, while no sound or reading indicates it’s blown.

4. Replace Blown Fuses

If a fuse is found to be blown, replace it with a new fuse of the same amperage rating. The amperage can usually be found on the fuse itself or in the owner's manual.
Push the new fuse into place until it is secure.

5. Reassemble and Test

After replacing any blown fuses, reattach the fuse box cover.
Turn on the ignition and test the electrical components to confirm they are functioning properly.
