Solution

1. Preparation

Gather necessary tools and replacement fuses.
Ensure the vehicle is turned off and parked on a level surface.
Disconnect the battery if necessary for safety.

2. Locate the Fuse Box

Engine Compartment Fuse Box:
- Open the hood and secure it.
- Remove the cover by releasing the clips or tabs.
Cabin Fuse Box:
- Open the driver's side door.
- Locate the fuse box cover beneath the dashboard.

3. Inspect the Fuses

Identify the specific fuse related to the malfunctioning component using the diagram on the fuse box cover or the owner's manual.
Remove the fuse using fuse pullers or needle-nose pliers.
Visually inspect the fuse for a broken filament. If damaged, it is blown.

4. Test the Fuse (if necessary)

Set the multimeter to continuity mode.
Place one probe on each terminal of the fuse.
If the multimeter beeps or shows continuity, the fuse is good. If not, it is blown.

5. Replace the Fuse

If the fuse is blown, replace it with a new fuse of the same amperage rating.
Reinstall the fuse cover securely.
Reconnect the battery if it was disconnected.
