Reasons Why 05.5 Volkswagen Jetta Auto Headlights Not Working

Burnt-out Headlight Bulbs

The most common reason for headlights not working is a burnt-out bulb. To check if this is the case, look at the headlights and see if any of the bulbs are dark or appear to be out. If so, you will need to replace the bulb.

Faulty Headlight Switch

The headlight switch is responsible for turning the headlights on and off. If the switch is faulty, it may not be able to properly send power to the headlights, causing them to not work. To check if the switch is the problem, turn the headlights on and off with the key in the ignition. If the headlights do not turn on or off when you turn the switch, the switch is likely faulty and will need to be replaced.

Bad Wiring

The wiring that connects the headlights to the battery and the headlight switch can become damaged or corroded, which can prevent the headlights from getting power. To check if the wiring is the problem, inspect the wiring harness for any damage or corrosion. If you find any damage, you will need to repair or replace the wiring.

Blown Fuse

A blown fuse can also prevent the headlights from working. To check if a fuse is blown, look in the fuse box for a fuse that is labeled headlights or headlight circuit. If the fuse is blown, you will need to replace it with a new fuse.
