What are the reasons for the Volkswagen Jetta's headlights not working?
2 Answers
The reasons for the Volkswagen Jetta's headlights not working are: 1. The headlight fuse or bulb is burned out; 2. Poor contact in the wiring. Taking the 2019 Volkswagen Jetta VS5 as an example, its body dimensions are: length 4419mm, width 1841mm, height 1616mm, wheelbase 2630mm, fuel tank capacity 51L, and body structure is a 5-door, 5-seat SUV. The 2019 Volkswagen Jetta VS5 is equipped with a 1.4T turbocharged engine, with a maximum power of 110kW and a maximum torque of 250Nm, paired with a 5-speed manual transmission.
The headlights on my Volkswagen Jetta aren't working, which is really annoying as I encountered the same issue last year. Common causes include burnt-out bulbs, especially in older cars where the bulb lifespan has expired and filaments are prone to breaking. Blown fuses are the most frequent issue—open the fuse box and check the corresponding headlight fuse. Wiring faults like short circuits or open circuits may occur due to aging wires or loose connections in the Jetta. A faulty relay or malfunctioning headlight switch can also interrupt the current. Voltage instability might stem from alternator issues. Remember to check the fuse first, as it's the easiest and cheapest to replace. If the problem persists, visit a professional repair shop to test the circuit to avoid nighttime driving hazards. Regular maintenance can prevent these issues, and cleaning the headlight connectors is also effective.
