Solution

1. Preparation

Tools Required:
- Fuse puller or needle-nose pliers
- Multimeter (if testing fuses)
Safety Warnings:
- Ensure the vehicle is turned off and the keys are removed from the ignition.

2. Locate the Fuse Box

Open the driver's side door and locate the fuse box cover, usually positioned under the dashboard or near the driver's side kick panel.
Remove the fuse box cover by gently pulling it off or unscrewing it, depending on the design.

3. Identify the Blown Fuse

Refer to the fuse diagram located on the inside of the fuse box cover or in the owner's manual.
Find the fuse related to the malfunctioning component and visually inspect it.
If the fuse appears blackened or the wire inside is broken, it is blown.

4. Replace the Blown Fuse

Use a fuse puller or needle-nose pliers to carefully remove the blown fuse.
Select a new fuse of the same amperage rating (as indicated on the fuse diagram).
Insert the new fuse into the same slot, ensuring it is firmly seated.

5. Reassemble and Test

Replace the fuse box cover and ensure it is secured properly.
Start the vehicle and test the previously malfunctioning electrical components to confirm they are now functioning correctly.
