Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Access the Fuse Box

Locate the fuse box in the cabin (usually under the dashboard on the driver's side) and/or under the hood.
Remove the fuse box cover by unclipping or unscrewing it, depending on the design.

3. Remove the Blown Fuse

Identify the blown fuse using the diagram on the fuse box cover or the owner's manual.
Use a fuse puller or needle-nose pliers to carefully remove the blown fuse from its socket.

4. Install the New Fuse

Select a new fuse that matches the amperage rating of the blown fuse (found on the fuse itself and indicated in the owner's manual).
Insert the new fuse firmly into the same socket, ensuring it is seated correctly.

5. Reassemble and Test

Replace the fuse box cover, ensuring it is securely attached.
Reconnect the negative battery terminal.
Start the vehicle and test the electrical components to ensure they function correctly.
