Solution

1. Preparation

Gather necessary tools: multimeter, fuse puller, and replacement fuses.
Ensure the vehicle is turned off and parked on a level surface.

2. Locate and Access the Fuse Box

Open the driver's door and locate the fuse panel cover on the left side of the dashboard.
Remove the cover by pulling it off gently.

3. Inspect and Test the Fuses

Using your fingers or a fuse puller, remove each fuse one at a time, starting from the top.
Check the fuse visually for a broken filament or discoloration.
For further verification, use the multimeter to test continuity:
- Place one probe on each end of the fuse.
- If the multimeter beeps or shows continuity, the fuse is good; if not, replace it.

4. Replace Blown Fuses

Obtain replacement fuses that match the amperage of the blown fuses as per the owner's manual.
Insert the new fuses into their respective slots securely.
Ensure the fuse box cover is properly reattached.

5. Final Checks

Close the driver's door and turn the ignition to the "ON" position without starting the engine.
Test the electrical components that were previously malfunctioning to ensure they are functioning correctly.
