Solution

1. Preparation

Gather necessary tools: fuse puller (or needle-nose pliers), replacement fuse (with the same amperage), and a flashlight.
Ensure the vehicle is off and the keys are removed from the ignition for safety.

2. Access the Fuse Box

Open the driver's side door and remove the fuse box cover by either unclipping or unscrewing it, depending on your model.
If the fuse box is located in the engine compartment, open the hood and secure it.

3. Remove the Blown Fuse

Using the fuse puller or needle-nose pliers, carefully grasp the blown fuse and pull it straight out of the socket.
Inspect the fuse to confirm it is blown before disposing of it.

4. Install the New Fuse

Take the replacement fuse and ensure it matches the amperage rating of the blown fuse (indicated on the fuse and fuse box diagram).
Insert the new fuse into the same slot, ensuring it is seated firmly.

5. Reassemble and Test

Reattach the fuse box cover securely.
Start the vehicle and test the electrical components that were previously not functioning to ensure they are operational.
