Solution

1. Preparation

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

2. Remove the Headlight Assembly

Open the hood and locate the headlight assembly.
Remove the screws or clips securing the headlight assembly (use a socket set).
Gently pull the assembly out of the housing, being cautious of any electrical connectors.

3. Inspect and Replace Bulbs

Check the bulb sockets for corrosion or damage.
Remove the burnt-out bulb by turning it counterclockwise.
Install the new bulb (ensure it is the correct type for the G70) by turning it clockwise until secure.
Avoid touching the glass of the new bulb with bare hands to prevent oil contamination.

4. Check Wiring and Connectors

Inspect the wiring harness for wear or broken wires.
Clean any corrosion from the connectors using electrical contact cleaner.
Repair any damaged wiring and ensure all connectors are secure.

5. Reinstall Headlight Assembly

Place the headlight assembly back into its housing.
Secure it with the screws or clips removed earlier.
Reconnect any electrical connectors that were disconnected.

6. Reconnect Battery and Test

Reconnect the battery terminals securely.
Turn on the headlights to verify functionality and check for flickering or dimming.
