Diagnostic Steps

Open the front trunk (frunk) to access the fuse box.
2
Locate the fuse box cover and remove it to reveal the fuses.
3
Refer to the fuse diagram located on the inside of the fuse box cover to identify the specific fuses related to the malfunctioning components.

Solution

1. Preparation

Gather tools: flathead screwdriver, multimeter, and safety gloves.
Ensure the vehicle is in park and power is turned off.

2. Access the Fuse Box

Open the front trunk (frunk) by pulling the release lever inside the vehicle.
Locate the fuse box cover; it is usually located on the left side of the frunk.
Use a flathead screwdriver to carefully pry off the fuse box cover.

3. Inspect Fuses

Refer to the fuse diagram on the inside of the fuse box cover to locate the specific fuses for the malfunctioning components.
Visually inspect each fuse for damage. If a fuse is broken or burnt out, it will need replacement.

4. Test Fuses (if necessary)

For fuses that look intact but still may not be functioning, use a multimeter:
- Set the multimeter to the continuity setting.
- Place one lead on each side of the fuse. A beep indicates the fuse is good; no sound indicates a blown fuse.

5. Replace Damaged Fuses

Remove any blown fuses using fuse pullers or needle-nose pliers.
Replace with new fuses of the same amperage rating as indicated on the fuse diagram.
Reattach the fuse box cover securely.
