2. Remove the cover of the fuse box by releasing the clips or screws as indicated in the owner's manual.

3. Inspect the Fuses

Sub-steps:
1. Identify the fuses related to the malfunctioning components using the diagram on the fuse box cover.
2. Using the fuse puller or needle-nose pliers, carefully remove each fuse one at a time.
3. Visually inspect each fuse for damage.
