Why 05.5 Volkswagen Jetta Auto Head Lights Not Working

Headlight Switch

The headlight switch is a common cause of auto headlights not working on a Volkswagen Jetta. The switch can become faulty and stop sending power to the headlights. To check the headlight switch, you can use a multimeter to test for continuity between the switch and the headlights. If there is no continuity, the switch will need to be replaced.

Headlight Wiring

The wiring between the headlight switch and the headlights can also be a cause of auto headlights not working. The wiring can become damaged or corroded, which can prevent power from reaching the headlights. To check the wiring, you can use a multimeter to test for continuity between the switch and the headlights. If there is no continuity, the wiring will need to be repaired or replaced.

Headlight Ballast

The headlight ballast is a device that regulates the flow of electricity to the headlights. If the ballast is faulty, it can cause the headlights to flicker or not work at all. To check the ballast, you can use a multimeter to test for continuity between the ballast and the headlights. If there is no continuity, the ballast will need to be replaced.

Headlight Bulbs

The headlight bulbs are another common cause of auto headlights not working on a Volkswagen Jetta. The bulbs can burn out or become damaged, which can prevent them from producing light. To check the bulbs, you can remove them from the headlights and inspect them for damage. If the bulbs are damaged, they will need to be replaced.
