Why is my left low beam not working?
Why is my left low beam not working?
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. Consult your owner’s manual to locate the main fuse for the headlight circuit and replace that fuse with one having the same amp rating.
How do you fix a low beam fault?
4 Steps to Fix a Low Beam Headlight Bulb
- Find the blown out bulb.
- Buy the replacement bulb.
- Get your tools ready.
- Disconnect the negative terminal on the battery.
- Remove the trim pieces.
- Find the headlight holder.
- Disconnect the cables from the headlight.
- Remove the headlight bulb from the bulb housing.
Are high beams and low beams on the same circuit?
On some vehicles, the headlights are wired so if one goes out, the other does as well. That means a bad connection from corrosion could cause the headlights to go out. Since the high beams are on a different circuit, they often work just fine even when the low beams stop working.
Are both headlights on the same fuse?
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.
Which fuse is for the low beam?
Low beam fuses are #38 and #39 in the IPDM fuse box.
Does each headlight have a 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.
How do you check a headlight circuit?
How to Check That Power Is Getting to the Headlights: Use a Test Light
- Unplug the light bulb electrical connector.
- Turn on the headlights.
- Connect your test light to a good ground and touch the test light probe to the power side of the connector terminal.
Which relay controls the headlights?
The headlight relay is typically located in the power distribution box in the engine compartment.
How do I know if my headlight relay is bad?
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.
What fuse is for headlights?
Your average high beam (for a normal headlight) is 55 or 65 watts. In a 12 V circuit, that’s less than 6 amps nominally. If you put in a 10 amp fuse, you should be ok.
What is the most common reason for a headlight failure?
Most total headlight failures are caused by a bad component like a fuse, relay, or module. Wiring problems can also cause both headlights to stop working. The high beams and/or the low beams don’t work.
Why do my low beams not work but high beams do?
Since the low beams are used the most, they tend to burn our much sooner than the high beams. If your low beams stop working but the high beams still turn on, there’s a good chance that simply replacing the headlight bulbs with new OEM headlights will solve the problem.
Is there a fuse for low beam lights?
Headlight Fuse or Relay is Bad 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.
