2. Locate the Fuse Box

Open the driver’s side door and locate the fuse box cover, typically found on the left side of the dashboard or under the hood.
Remove the cover by gently pulling it off or unscrewing any screws if applicable.

3. Identify and Remove the Blown Fuse

Refer to the fuse diagram on the inside of the fuse box cover or in the owner’s manual to locate the specific fuse for the malfunctioning component.
Use a fuse puller or needle-nose pliers to grasp the blown fuse and pull it straight out of the socket.

Take the replacement fuse and insert it into the same slot where the blown fuse was located, ensuring it is seated firmly.
Double-check that the amperage rating of the new fuse matches the original.

Replace the fuse box cover securely.
Start the vehicle and check the previously non-functioning electrical components to ensure they are operating correctly.
