Solution

1. Preparation

Gather tools and materials: fuse puller (or needle-nose pliers), multimeter, replacement fuses.
Ensure the vehicle is turned off and the key is removed from the ignition.

2. Access the Fuse Box

Open the driver’s side door and locate the access panel for the fuse box under the dashboard.
If necessary, remove the cover by gently prying it off or unscrewing it, depending on the design.

3. Inspect Fuses

Use the fuse puller or needle-nose pliers to carefully remove each fuse one at a time.
Visually check each fuse for signs of damage such as a broken wire or discoloration.

4. Test Fuses with Multimeter

Set the multimeter to the continuity setting.
Place one probe on each end of the fuse. If the multimeter beeps or shows a reading, the fuse is good. If not, it needs to be replaced.

5. Replace Blown Fuses

Refer to the owner’s manual to confirm the correct fuse rating.
Insert a new fuse in the same slot as the blown fuse.
Ensure it is seated properly and securely in the fuse box.

6. Reassemble and Test

Reattach the fuse box cover.
Turn on the vehicle and test the electrical components to confirm functionality.
