Use a fuse puller or needle-nose pliers to carefully grasp the blown fuse.
Pull the fuse straight out of the socket to avoid damaging the surrounding components.

5. Install the New Fuse

Select a new fuse of the correct amperage, as indicated in the owner’s manual or on the fuse box diagram.
Insert the new fuse firmly into the socket, ensuring it is seated properly.

6. Reassemble and Test
