Diagnostic Steps

1
Open the front trunk to access the fuse box located under the dashboard.
2
Refer to the owner’s manual for the fuse layout and specific fuse designations.
3
Inspect the fuses visually for any signs of damage, such as a broken filament or discoloration.
4
Use a multimeter to check continuity on any suspicious fuses.
5

Solution

1. Preparation

Gather necessary tools and materials.
Tools Required:
- Fuse puller or needle-nose pliers
- Multimeter (for continuity testing)
Ensure the vehicle is parked on a level surface and powered off.

2. Accessing the Fuse Box

Open the front trunk and locate the fuse box cover beneath the dashboard.
Carefully remove the cover by pulling it straight off or unscrewing any fasteners if applicable.

3. Inspecting the Fuses

Use the owner’s manual to identify the fuses related to the malfunctioning components.
Visually inspect each fuse for damage or blown filaments.
For fuses that appear intact but are still suspected to be faulty, proceed to continuity testing.

4. Testing Fuses

Set the multimeter to the continuity setting.
Place one probe on each terminal of the fuse.
- If the multimeter beeps or displays continuity, the fuse is good.
- If there is no beep or reading, the fuse is blown and needs replacement.

5. Replacing Blown Fuses

Using a fuse puller or needle-nose pliers, carefully remove any blown fuses.
Replace them with new fuses of the same amperage rating, ensuring they fit securely.
Reinstall the fuse box cover and close the front trunk.
