Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to avoid electrical shock.

2. Inspect and Replace Bulbs

Locate the headlight assembly by opening the hood.
Remove the headlight assembly cover by unscrewing or unclipping it.
Pull out the headlight bulb socket and inspect the bulb.
- If the bulb is burnt out, replace with a new bulb of the same specification (check owner's manual for specifics).
Reinsert the socket and secure the headlight assembly cover.

3. Test and Replace Headlight Relay

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Identify the headlight relay (refer to the fuse box diagram).
Remove the relay and test for continuity with a multimeter.
- If the relay fails the test, replace it with a new relay of the same type.
Reinstall the relay in the fuse box.

4. Check Wiring and Connectors

Inspect the wiring harness connected to the headlight assembly for frays, corrosion, or loose connections.
Clean any corroded connectors using electrical contact cleaner.
Repair or replace any damaged wiring as necessary.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Turn on the ignition and activate the headlights to check functionality.
If headlights work, proceed with final assembly; if not, further diagnosis may be necessary.
