Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and turn off the ignition.
Disconnect the battery to prevent electrical shock.

Tools Required:

Fuse puller
Multimeter
Socket set
Screwdriver set
OBD-II scanner

2. Inspect and Replace Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the fuses associated with the lighting system using the diagram on the fuse box cover.
Use a fuse puller to remove the fuses and visually inspect them for continuity; replace any blown fuses with the same amperage rating.

3. Check and Replace Bulbs

Access the exterior light assemblies by removing screws or clips as necessary.
Carefully remove the bulbs from their sockets and inspect them for any signs of burn-out or damage.
Replace any faulty bulbs with new ones, ensuring they are the correct type for the specific light assembly.

4. Test Wiring and Connections

Use a multimeter to check for voltage at the light sockets while someone activates the lights.
If voltage is present but the lights do not work, check the ground connections for corrosion or looseness.
Inspect the wiring harness for any signs of wear, fraying, or disconnection; repair or replace damaged sections as needed.

5. Verify Switch Functionality

Remove the headlight switch from the dashboard by unscrewing or unclipping it.
Test the switch with the multimeter for continuity; replace it if it shows no continuity when activated.
