1. Preparation

Gather tools and materials: replacement fuse, fuse puller or needle-nose pliers, multimeter.
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Locate the Fuse Box

Open the driver's side door and remove the cover panel on the side of the dashboard to access the interior fuse box.
Alternatively, open the hood to check the engine compartment fuse box, depending on the component affected.

Use a fuse puller or needle-nose pliers to gently remove the blown fuse.

4. Install the New Fuse

Select a replacement fuse of the same amperage rating as the blown fuse (check the markings on the fuse).
Insert the new fuse into the same slot where the old fuse was removed, ensuring it is seated securely.

5. Reassemble and Test
