Solution

1. Preparation

Gather necessary tools: fuse puller or needle-nose pliers, multimeter, replacement fuses.
Ensure the vehicle is turned off and parked on a flat surface.

2. Locate the Fuse Box

Open the driver's side door and locate the fuse box, which is typically located on the side of the dashboard or under the steering column.
Remove the fuse box cover by unclipping it or unscrewing it, if applicable.

3. Inspect and Test Fuses

Identify the fuses related to the malfunctioning electrical components using the diagram on the fuse box cover or the owner's manual.
Use the multimeter to check each fuse for continuity. If the multimeter shows a reading of zero or infinity, the fuse is blown.

4. Replace the Blown Fuse

Use the fuse puller or pliers to remove the blown fuse carefully.
Check the amperage rating on the fuse and select a replacement fuse of the same rating.
Insert the new fuse into the correct slot firmly until it fits snugly.

5. Reassemble and Test

Reattach the fuse box cover securely.
Turn on the vehicle and test the electrical components to ensure they are functioning properly.
