Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is turned off and parked in a safe location.
Disconnect the battery to prevent any electrical shocks.

2. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the front grille lights, using the vehicle’s manual for reference.
Remove the fuse using a fuse puller.
Inspect the fuse; if it's blown, replace it with a new one of the same amperage.
Reconnect the battery.

3. Replace Front Grille Light Bulbs

Access the front grille by removing any necessary panels or covers.
Gently twist and pull the light bulb socket out of the grille assembly.
Remove the old bulb and replace it with a new, compatible LED bulb.
Reinsert the socket back into the grille assembly and ensure it's secured.

4. Repair Wiring and Connections

Inspect the wiring harness for any visible damage or corrosion.
If any wires are damaged, splice in new wiring using solder and heat-shrink tubing, or replace the entire harness if necessary.
Clean any corroded connections using a contact cleaner.

5. Testing

Reconnect the battery and turn on the vehicle.
Activate the exterior lights to check if the front grille lights illuminate.
If the lights still do not work, recheck all connections and components.
