Why is my high beam not working?
By far the most common reason your brights will stop working is from a blown fuse or a bad relay. Or, it could be a bad relay. If the headlight relay has failed, it may not respond when you attempt to switch the high beams on. Replacing the relay should restore the system and get your high beams working once again.
Are high beams and low beams on the same fuse?
Like all electrical systems, the headlights in your vehicle have a fuse in the circuit to prevent too much electricity from reaching the bulb. There will also be a headlight relay that switches power from the low beams to the high beams. If the fuse goes bad, you likely won’t have any headlights at all.
Can a fuse cause a headlight not to work?
Solution: If both headlights aren’t working, it’s unlikely that a bulb is at fault. The likely cause is a fuse, headlight relay, headlight switch, dimmer switch or a wiring fault. About the only cause that is an easy fix is a blown fuse.
Are there separate fuses for each headlight?
Depending on how your headlight circuit is set up, there may be one fuse or multiple fuses for the headlights. If you find a blown fuse, then replacing it may fix the problem. When replacing a blown headlight fuse, it’s important to use a new one with the same amperage rating.
Do high beams have a fuse?
Blown High Beam Fuse Fuses protect the wiring from circuit problems, such as short circuits. A fuse protects the wiring from damage, in case too much current is being drawn through the high beam circuit.
Why do my high beams work but not low beams?
Headlight Fuse or Relay If a headlight fuse blows, it could cause the headlights to stop working. Most headlight systems are also designed with a relay that switches the power between low beam and high beam headlights. If this relay goes bad, it could allow power to the high beams, but not the low beams.
Why do I have high beams but no low beams?
Where are headlight fuses located?
The front of the dash panel has a fuse panel on it.
How do I know if my high beam relay is bad?
Headlights Don’t Turn On The most common sign of a bad headlight relay is headlights that don’t work. A headlight relay will typically fail in the open position, preventing voltage from reaching the headlights. If the low beam relay fails, the low beams won’t work.
