Solution
1. Preparation
  • Gather tools: Multimeter, socket set, screwdrivers, replacement bulbs, replacement fuse if needed.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Inspect and Replace Bulbs
  • Locate the fog light assembly. This typically requires removing the cover or accessing from underneath the vehicle.
  • Remove the fog light bulb from the socket:
    • Turn the bulb counterclockwise to release it.
    • Inspect the bulb for any signs of burning or damage.
  • If damaged, replace with a new bulb of the same type (usually H11 for Honda CR-V).
  • Reinstall the new bulb by turning it clockwise until it locks in place.
3. Check and Replace Fuse
  • Locate the fuse box, usually found under the dashboard or in the engine compartment.
  • Identify the fog light fuse (check the diagram on the fuse box cover).
  • Remove the fuse and inspect it:
    • If the metal strip inside is broken, replace the fuse with one of the same amperage (typically 10A).
  • Reinstall the fuse and close the fuse box.
4. Test the Relay
  • Locate the fog light relay in the fuse box.
  • Remove the relay and visually inspect it for burns or damage.
  • Swap it with a similar relay (e.g., horn relay) to test functionality.
  • If the fog lights work with the swapped relay, replace the faulty relay.
5. Check Wiring and Connections
  • Inspect the wiring harness connected to the fog lights for any frays, breaks, or corrosion.
  • Ensure all connections are tight and free from rust.
  • Repair or replace any damaged wiring as necessary.
