Volkswagen Headlights Not Working: [Causes & Proven Solutions]

As a certified Volkswagen technician, I understand the frustration and inconvenience that can come with headlights that are not working. Not only is it a safety hazard, but it can also be a major inconvenience. This guide will help you troubleshoot the issue and get your headlights back up and running as quickly as possible.

The steps outlined in this guide are designed to help you diagnose the problem and identify the necessary repairs. However, if you are not comfortable working on your vehicle, it is always best to have a qualified technician take a look.

Why Volkswagen Headlights Not Working

Burnt out light bulbs

The most common reason for Volkswagen headlights not working is a burnt out light bulb. This can happen for a number of reasons, including:

Old age: Light bulbs have a limited lifespan, and will eventually burn out.
Overheating: If the headlights are left on for too long, they can overheat and burn out.
Damage: Light bulbs can be damaged by road debris, such as rocks or gravel.

To check if a light bulb is burnt out, simply turn on the headlights and look at the bulb. If the filament is broken, the bulb is burnt out and will need to be replaced.

Loose or corroded wiring

Another common cause of Volkswagen headlights not working is loose or corroded wiring. This can happen if the wiring is damaged by road debris, or if it is not properly secured.

To check the wiring, look for any signs of damage or corrosion. If you find any damage, you will need to repair or replace the wiring.

Faulty headlight switch

The headlight switch is responsible for turning the headlights on and off. If the headlight switch is faulty, the headlights may not turn on even if the bulbs are working properly.

To check the headlight switch, turn on the headlights and listen for a clicking sound. If you do not hear a clicking sound, the headlight switch may be faulty and will need to be replaced.

Faulty headlight relay

The headlight relay is a small electrical device that controls the flow of electricity to the headlights. If the headlight relay is faulty, the headlights may not turn on even if the switch is turned on.

To check the headlight relay, turn on the headlights and listen for a clicking sound. If you do not hear a clicking sound, the headlight relay may be faulty and will need to be replaced.

Faulty fuse

A fuse is a small electrical device that protects the electrical system from damage. If a fuse blows, it will stop the flow of electricity to the headlights.

To check the fuse, look in the fuse box for a fuse that is labeled headlights or headlamps. If the fuse is blown, it will need to be replaced.

How to Troubleshoot: Volkswagen Headlights Not Working

Step 1: Check the Fuses

The first thing you should do if your Volkswagen headlights are not working is check the fuses. Fuses are small, cylindrical devices that protect your car’s electrical system from damage. If a fuse blows, it will prevent power from flowing to the headlights.

To check the fuses, you will need to locate the fuse box. The fuse box is usually located under the hood of your car. Once you have found the fuse box, open it and look for the fuses that are labeled for the headlights.

To check a fuse, use a voltmeter or a test light. If the fuse is blown, the voltmeter or test light will not show any voltage. If the fuse is not blown, the voltmeter or test light will show voltage.

If a fuse is blown, you will need to replace it with a fuse of the same amperage. You can find fuses at most auto parts stores.

Step 2: Check the Headlight Switch

The next thing you should check is the headlight switch. The headlight switch is located on the dashboard of your car. To check the headlight switch, turn the key to the On position and turn the headlight switch to the On position. If the headlights do not come on, the headlight switch may be faulty.

To test the headlight switch, you will need a multimeter. Connect the multimeter to the headlight switch terminals. Turn the headlight switch to the On position. The multimeter should show continuity. If the multimeter does not show continuity, the headlight switch is faulty and will need to be replaced.

Step 3: Check the Headlight Wiring

The next thing you should check is the headlight wiring. The headlight wiring runs from the headlight switch to the headlights. To check the headlight wiring, you will need to use a voltmeter or a test light.

With the key in the On position, turn the headlight switch to the On position. Use the voltmeter or test light to check for voltage at the headlight connectors. If there is no voltage at the headlight connectors, the headlight wiring is faulty and will need to be repaired or replaced.

Step 4: Check the Headlights

The final thing you should check is the headlights themselves. To check the headlights, you will need to remove the headlight bulbs. Once you have removed the headlight bulbs, inspect them for damage. If the headlight bulbs are damaged, they will need to be replaced.

If you have checked all of the above and your Volkswagen headlights are still not working, you will need to take your car to a qualified mechanic.
