Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and in "Park" or "Neutral."
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace Fog Light Bulbs

Tools Required: Socket set, screwdriver.
Remove the fog light assembly by unscrewing the retaining screws or bolts.
Pull the fog light bulb out of the socket carefully.
Inspect the bulb; if it's burnt out, replace it with a new bulb of the same type (typically H11 for the Camry XV50).
Reinstall the fog light assembly securely.

3. Inspect and Replace the Fog Light Fuse

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box (usually found under the dashboard or in the engine compartment).
Identify the fog light fuse (refer to the diagram on the fuse box cover).
Remove the fuse and inspect for any damage.
If the fuse is blown, replace it with one of the same amperage (typically 15A).

4. Test and Replace the Fog Light Switch (if necessary)

Tools Required: Multimeter, socket set.
Reconnect the negative battery terminal.
Use a multimeter to test the fog light switch for continuity when engaged.
If the switch is faulty, remove the trim panel to access the switch.
Disconnect the wiring harness and replace the switch with a new one.
Reassemble the trim panel after the switch replacement.

5. Inspect Wiring and Connections

Tools Required: Electrical tape, wire connectors.
Visually inspect the wiring leading to the fog lights for any fraying or corrosion.
Repair any damaged wires by cutting, splicing, and using wire connectors.
Ensure all connections are tight and free from corrosion.
