Solution

1. Preparation

Tools Required:
- Fuse puller or needle-nose pliers
- Multimeter
Ensure the vehicle is powered off and parked safely.

2. Accessing the Fuse Box

Sub-steps:
1. Open the front trunk (frunk) by using the interior release switch or fob.
2. Locate the fuse box cover under the hood, usually near the front passenger side.
3. Remove the fuse box cover by gently pulling it off or unfastening any clips.

3. Checking the Fuses

Sub-steps:
1. Refer to the fuse diagram printed on the underside of the fuse box cover or in the owner's manual.
2. Identify the fuse linked to the malfunctioning component.
3. Using the fuse puller or pliers, gently pull the fuse from its socket.
4. Visually inspect the fuse for any signs of a blown filament.
5. If using a multimeter, set it to the continuity setting and touch the probes to each end of the fuse. A continuous beep indicates a good fuse.

4. Replacing the Fuses

Sub-steps:
1. If a fuse is blown, obtain a replacement fuse of the same amperage (noted on the fuse).
2. Insert the new fuse into the same slot, ensuring it is seated properly.
3. Replace the fuse box cover securely.
4. Close the frunk and power on the vehicle to check if the issue is resolved.
