why are my Genesis G70 headlights flickering at night?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is off.
• Disconnect the battery to ensure safety.

2. Inspect and Replace Headlight Bulbs

• Remove the headlight assembly cover by unscrewing the retaining screws.
• Disconnect the electrical connector from the headlight bulb.
• Remove the faulty bulb by turning it counterclockwise and pulling it out.
• Insert the new bulb, ensuring it is seated properly and secure.
• Reconnect the electrical connector and replace the headlight assembly cover.

3. Check and Repair Wiring

• Visually inspect the wiring harness for any damage or loose connections.
• Use electrical cleaner to clean any corroded connectors.
• Repair or replace any damaged wires using appropriate gauge wire and connectors.
• Ensure all connections are snug and secure.

4. Test Voltage and Ground

• Reconnect the battery.
• Use a multimeter to measure the voltage at the headlight connectors while the headlights are on; it should read close to battery voltage (12-14 volts).
• If voltage is low, check the battery and alternator output.
• Inspect the ground connection; clean and tighten as necessary.
