How can you tell if a headlight bulb is blown?
Identify a blown out bulb. You can often tell when a headlight blows out while you’re driving, but confirm which bulb has actually blown out by leaving your headlights on and getting out of the vehicle to check. Then get back in your vehicle and turn on your high beams.
What number is the fuse to low beam right side?
F15 (25 Amp) controls left low beam, F11 (25 Amp) controls right low beam. Each fuse feeds a circuit in the Body Control Module. This circuit is listed as Micro, which means to me to be some electonics package. There are other fuses in the BCM that feed headlamp assemblys, rear lamp assemblies, markers and other lighting.

Which fuse is for headlights?
Headlights do not have fuses. They have circuit breakers (thermal cutoffs) ususally in the headlight switch. Headlight circuits aren’t fused because once the fuse blows, you’re out of luck. At least with a self-resetting breaker, when the circuit cools off, you again have light.
One of the first symptoms of a bad or failing headlight bulb is dim headlights. Over time headlight bulbs can wear out and begin to shine noticeably dimmer than when they were new. A dim headlight will not provide proper illumination and is also usually a sign that the bulb is approaching the end of its service life.
Do fuses affect headlights?
All the electrical systems in your car, including the headlights, are protected with fuses. These are designed to ‘blow’ and break the circuit if too much power comes through them. This protects all the components on the circuit. If a headlight fuse blows, it could cause the headlights to stop working.
How can you tell if a headlamp Fuse has blown?
Where there is a fuse fitted in the headlamp circuit , check it to see if it has blown (See Working on the wiring system ). Circuits can be overloaded by adding extra driving lamps, or installing bulbs that are too powerful in the main lamps.
What to look for when checking headlamps and lights?
Checks on wiring and connections must include the spring-loaded contacts, where that type of bayonet bulb holder has been used. A sticking plunger could result in the failure of the lights in that unit, while failure of an insulating washer could mean a short circuit and a dimming of all the lights, or cause a fuse to blow.
What to do if your headlight Fuse has melted?
Check your car’s owner’s manual for information on how to access the fuses and where they are located. Check for melted wires leading to any of the fuses, and replace said fuses if necessary. Use a voltmeter to make sure that power is actually running to your headlight.
What should I do if my headlight is not working?
Unplug the light, pull the switch, and see if the fuse blows. If not, the problem is not in the wiring. Make sure you have purchased the correct wattage of bulb. Ensure that you do not have a faulty or damaged bulb. Check and see if your high beam bulb is the issue. If so, replace it. Check all wired connections and look for any exposed wiring.
