2
Turn off the ignition and ensure all electrical components are powered down.
3
Open the fuse box cover and visually inspect for blown fuses (look for a broken filament or discoloration).

Solution

1. Preparation

Gather necessary tools (multimeter, fuse puller, flashlight).
Ensure the vehicle is parked on a flat surface and is in the "off" position.

2. Locate the Fuse Box

For the Skoda Octavia NFL, the main fuse box is typically located in the driver's side dashboard.
Open the driver's door, and remove the cover panel located on the left side of the dashboard.

3. Inspect Fuses

Using a fuse puller, carefully remove each fuse one at a time.
Check each fuse visually for a broken filament. If the filament is intact, it is likely good.
If any fuses appear damaged, use a multimeter set to continuity mode to confirm functionality.

4. Replace Blown Fuses

Take note of the amperage rating of the blown fuses. Replace them with new fuses of the same rating.
Ensure that the replacement fuses are properly seated in their slots.

5. Reassemble and Test

Reattach the fuse box cover securely.
Turn on the ignition and test the electrical components to ensure they are functioning correctly.
