Solution

1. Preparation

Gather necessary tools: fuse puller, multimeter, and replacement fuses.
Ensure the vehicle is turned off and parked on a flat surface.
Disconnect the battery to avoid any electrical shock or short circuit.

2. Locate the Fuse Box

Open the driver’s side door and locate the fuse box cover, typically on the left side of the dashboard.
Remove the cover by pressing the release tabs or unscrewing, if necessary.

3. Remove the Blown Fuse

Using a fuse puller or needle-nose pliers, carefully remove the blown fuse.
Inspect it to ensure it is indeed blown (the metal strip inside should be broken).

4. Install New Fuse

Select a new fuse of the same amperage (refer to the fuse diagram).
Insert the new fuse into the same slot where the blown fuse was located.
Ensure it is seated properly.

5. Reassemble and Test

Reattach the fuse box cover securely.
Reconnect the battery.
Turn on the vehicle and test the affected components to ensure they are functioning.
