Solution

1. Preparation

Gather necessary tools: flat-head screwdriver or fuse puller, multimeter.
Ensure the vehicle is turned off and parked safely.

2. Locate Fuse Boxes

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

3. Inspect Fuses

Visual Inspection: Remove the cover and use your fingers or a fuse puller to gently pull out the fuses one at a time.
- Check for a broken metal strip inside the fuse; if broken, it indicates a blown fuse.
- Look for discoloration or charring around the fuse terminals.

4. Test Fuses with Multimeter

Set the multimeter to the continuity setting.
Touch the probes to both terminals of the fuse:
- If the multimeter beeps or shows a reading close to zero, the fuse is good.
- If there is no continuity, the fuse is blown and needs replacement.

5. Replace Blown Fuses

Remove the blown fuse and replace it with a new fuse of the same amperage (consult the fuse box diagram for the correct rating).
Reinsert all fuses securely and replace the fuse box covers.
