Solution
1. Preparation
  • Gather tools: socket set, multimeter, replacement fog light bulbs, fuse puller.
  • Disconnect the vehicle's battery to ensure safety while working on electrical components.
2. Inspect and Replace Bulbs
  • Remove the fog light assembly:
    • Use a socket set to unfasten the screws holding the fog light in place.
    • Carefully pull out the fog light assembly.
  • Replace the bulb:
    • Twist the bulb socket counterclockwise to remove it from the assembly.
    • Replace with a new bulb, ensuring it is the correct type and wattage.
    • Reinstall the bulb socket by twisting it clockwise.
3. Check and Replace Fuse
  • Locate the fuse box (consult the owner's manual for location).
  • Remove the fog light fuse using a fuse puller.
  • Inspect the fuse for continuity; replace with an identical fuse if blown.
  • Reinsert the fuse into the fuse box.
4. Inspect and Repair Wiring
  • Visually inspect the wiring harness leading to the fog lights:
    • Look for frayed or damaged wires.
    • Repair any damaged sections using electrical tape or heat-shrink tubing.
  • Ensure all connectors are secure and free from corrosion.
5. Test Relay
  • Locate the fog light relay in the fuse box.
  • Swap it with a similar relay (if available) to check if the issue persists.
  • If the fog lights work with the swapped relay, replace the faulty relay with a new one.
