Solution

1. Preparation

Gather tools and materials.
Disconnect the battery to prevent electrical shorts.

Tools Required:

Multimeter
Socket set
Screwdriver set
OBD-II scanner
Relay tester

2. Inspect and Replace Fog Light Bulbs

Open the hood and locate the fog light assembly.
Remove the fog light cover (if applicable) using a screwdriver.
Unscrew the bulb socket from the fog light housing.
Pull out the old bulb and inspect for damage. Replace with a new bulb if necessary.
Reassemble the socket and cover.

3. Check and Replace Fog Light Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Find the fog light fuse and remove it using a fuse puller.
Inspect the fuse for continuity; if blown, replace it with a fuse of the same amperage (refer to owner’s manual for specific fuse rating).

4. Test Fog Light Switch

Reconnect the battery.
Use a multimeter to check for voltage at the fog light switch when turned on.
If no voltage is detected, the switch may need replacement.

5. Verify Relay Operation

Locate the fog light relay in the fuse box.
Remove the relay and test it with a relay tester or swap it with a similar relay (if applicable) to check functionality.
Replace the relay if it is found to be defective.
