Neither of my headlights are working, not even the low beams. I can't drive at night safely. The high beams seem to be working, though.

10 LösungenReplace Fuel Filter
Replace the fuel filter to ensure clean fuel is reaching the engine and sending unit.
Drain and Clean Fuel Tank
If fuel contamination is suspected, drain the fuel tank and clean out any sediment or debris.
Replace Instrument Cluster
If the fuel gauge is determined to be the faulty component, the entire instrument cluster may need to be replaced.
Test Fuel Gauge
Perform diagnostic tests on the instrument cluster to verify the functionality of the fuel gauge. This may involve applying known voltage signals.
Repair or Replace Wiring
Repair any damaged sections of the wiring or replace the affected harness if necessary.
Check Wiring Harness
Inspect the wiring harness connected to the fuel sending unit and the instrument cluster for any breaks, corrosion, or loose connections.
Replace Fuel Sending Unit
If the sending unit is found to be faulty, replace it with a new, compatible unit.
Inspect Fuel Sending Unit
Access the fuel tank and visually inspect the fuel sending unit for any signs of damage or corrosion. Test its resistance values.
Professional Fuel Injector Cleaning
Have the fuel injectors professionally cleaned and tested for optimal performance.
Use Fuel Injector Cleaner
Add a quality fuel injector cleaner to the fuel tank to help dissolve deposits.

Identifizierte Ursachen
Blown Low Beam Fuses
90%Each low beam circuit typically has its own fuse. If both fuses have blown simultaneously, it would explain why neither low beam is working.
Faulty Headlight Switch or Multi-Function Switch
75%The headlight switch or the multi-function switch (which often controls headlights, turn signals, and wipers) could have an internal fault that prevents power from reaching the low beams, while still allowing power to the high beams.
Wiring Harness Issue
60%There might be a break, short, or corrosion in the wiring harness that specifically feeds power to the low beam filaments, while the high beam wiring remains intact.
