Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Locate the Fuse Box

Open the driver's side door and locate the fuse box cover beneath the dashboard on the left side.
Remove the fuse box cover by pressing the clips or screws (if applicable).

3. Remove the Blown Fuse

Identify the blown fuse using the diagram on the inside of the fuse box cover or the owner's manual.
Use a fuse puller, needle-nose pliers, or your fingers to gently pull the blown fuse out of its socket.
Inspect the fuse; if the filament is broken or the fuse appears blackened, it is blown.

4. Install the New Fuse

Obtain a new fuse of the same amperage as the blown fuse (check the owner's manual for specifications).
Insert the new fuse firmly into the same socket where the old fuse was removed.

5. Reassemble and Test

Replace the fuse box cover securely.
Reconnect the negative terminal of the battery.
Start the vehicle and test the previously non-functioning component to ensure it operates correctly.
