my Skoda Octavia NFL (2020-Present) fog lights are not working, how can I fix them?

Solution

1. Preparation

• Gather tools: flathead screwdriver, Phillips screwdriver, multimeter, replacement bulbs (if necessary), and a fuse puller.
• Ensure the vehicle is parked on a flat surface and the engine is off.

2. Inspect and Replace Fog Light Bulbs

• Sub-steps:
  1. Open the hood and locate the fog light assembly.
  2. Remove the fog light assembly by unscrewing the retaining screws or clips.
  3. Disconnect the wiring harness from the assembly.
  4. Remove the old bulb by twisting it counterclockwise and pulling it out.
  5. Insert the new bulb by placing it in the socket and twisting it clockwise to secure it.
  6. Reconnect the wiring harness and reattach the fog light assembly.

3. Check and Replace the Fog Light Fuse

• Sub-steps:
  1. Locate the vehicle's fuse box (usually found under the dashboard or in the engine compartment).
  2. Refer to the fuse box diagram to identify the fog light fuse.
  3. Remove the fuse using a fuse puller and inspect it for continuity (a blown fuse will have a broken filament).
  4. Replace with a new fuse of the same amperage (typically 10A or 15A).

4. Test the Fog Light Switch

• Sub-steps:
  1. Remove the fog light switch from the dashboard by carefully prying it out.
  2. Use a multimeter to test for continuity across the switch terminals when activated.
  3. If the switch is faulty, replace it with a new one.

5. Inspect Wiring and Connectors

• Sub-steps:
  1. Visually inspect the wiring and connectors leading to the fog lights for any signs of wear, corrosion, or damage.
  2. Use a multimeter to check for continuity through the wires.
  3. Repair or replace any damaged wiring or connectors as necessary.
