Solution

1. Preparation

Gather tools and materials:
- Fuses of appropriate ratings
- Multimeter
- Flashlight (for better visibility)
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Locate Fuse Boxes

Under-Dashboard Fuse Box:
- Open the driver's side door and remove the cover panel under the dashboard on the left.
Engine Compartment Fuse Box:
- Open the hood and locate the fuse box near the battery.

3. Inspect Fuses

Visual Inspection:
- Remove the fuse panel cover.
- Check each fuse visually for signs of damage (broken filament or discoloration).
Continuity Test:
- Set the multimeter to the continuity setting.
- Remove the fuse and place the probes on the terminals. A beep indicates continuity; no beep indicates a blown fuse.

4. Replace Blown Fuses

Remove the blown fuses using fuse pullers or needle-nose pliers.
Insert new fuses of the same amperage rating into the appropriate slots.
Ensure the fuse is seated properly to prevent any loose connections.
