Solution

1. Preparation

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

2. Locate the Fuse Box

Open the driver’s door and remove the panel covering the fuse box, which is typically located on the driver’s side or under the dashboard.
Refer to the fuse diagram provided on the inside of the cover or in the owner’s manual to identify the blown fuse.

3. Remove the Blown Fuse

Using a fuse puller or needle-nose pliers, gently grasp the blown fuse and pull it straight out of the socket.
Inspect the fuse to confirm it is blown (the wire inside will be broken or blackened).

4. Install the New Fuse

Select a new fuse of the same amperage rating (found on the fuse itself or in the owner’s manual).
Insert the new fuse firmly into the socket, ensuring it is seated correctly.

5. Reassemble and Test

Replace the fuse box cover panel securely.
Reconnect the negative battery terminal.
Start the vehicle and test the electrical component to ensure it operates correctly.
