Headlight issue

ANSWER : Hello.

The daytime running lights are not supposed to function at the same time as the headlights. The daytime running lights are only supposed to come on during the day, to provide additional visibility for daytime driving, independently of the headlights. When the headlights are turned on the daytime running lights should turn off. If they are not turning on it may be possible that perhaps the bulbs have burned out, or there is an issue with the fuse or relay. If you run into any issues, consider contacting a certified technician, like one from YourMechanic, as certified technician can diagnose any issues with your lights firsthand and help you make the right repair.

ANSWER : Hello, thanks for writing in about your Nissan Frontier. The only way to tell if it is the light bulbs or the switch is to check for power to the bulbs when you switch to high beam. Most of the time both bulbs are bad. The connections to the bulbs could be faulty as well. If you’re unable to pinpoint the issue, have a certified technician, like one from YourMechanic, diagnose your lights firsthand for an accurate repair.

ANSWER : The common thread between the headlights and the signal lights is the combination switch. The combination switch controls your signal lights, turns the headlights on and off, as well as controls the high beam function. Most like;y the switch or wiring to the switch has an electrical short. This can cause constant power going to the functions the switch controls. While the combination switch is the most likely cause, wiring can also be a problem so I suggest having a certified technician look into the lights staying on to determine if there is a wiring issue before replacing any components. If the combination switch is found to be the culprit, the technician can replace it for you.

ANSWER : Hello. Ironically, I happen to have a 2000 CLK 430 as well and I experienced an almost identical scenario as you did. I had a fog light out on my vehicle, thinking it was a bulb I went ahead and replaced the light bulb but once I replaced it it still did not fix the issue. Upon further inspection of my vehicle I found that the some of the insulation around the wiring leading to the fog light was brittle and causing wires to be exposed. I taped the wires with some electrical tape because Mercedes-Benz has a very sensitive electrical system and if a wire is exposed it will cause resistance. If the electrical system senses too much resistance it will cut power off to that component to help protect other electrical parts. I suggest to have a technician such as one from YourMechanic inspect the wiring of your fog light that is out, check the fog light fuse in the side fuse compartment, and also check the clearance light bulb. The clearance light bulb is a small bulb located under the fog light and is integrated into the fog light circuit. If the clearance light is out it will interrupt the fog lights power. On my vehicle it was a clearance light being out and the damaged wiring to the fog light causing my fog light to be inoperative.

ANSWER : Hi there. Typically when you hear a grinding noise when you move forward or in reverse it’s usually an indication of a gear fault either in the transmission or another driveline component. If this occurs only when in reverse, it’s likely a damaged reverse gear. It is also possible that it’s a hydraulic fluid issue not supplying enough lubrication or pressure inside the lines to fully open the gear. I would recommend having a professional mechanic come to your location and complete a car is hard to shift inspection, so they can diagnose the source of your issue and recommend repairs that should resolve this problem.

ANSWER : If the area is fairly open, parts do not have to be removed to gain access to the terminals where the connector has to be repaired and if the broken wire is the only issue (defect) in that headlight circuit, the cost will be manageable. It would have to be looked at and estimated though so that there are no surprises (in particular, a technician would check for power in undamaged potion of circuit).

Sometimes there are pre-made wiring "pigtails" that are made just for these sorts of repairs because they are so common. That part, if available, might make sense as it provides a most durable and effective solution. You should ask about that possibility.

The bottom line is your car would have to be viewed in person to give you the best, most authoritative answer. Feel free to inquire further at YourMechanic and a mobile technician will be able to diagnose your headlight issue and fix your issue accordingly. Thanks for your question, headlights are important for safety!

ANSWER : Hi there. Over time, many different items can cause headlights to fade. In most cases, it’s a caused by debris that naturally builds up on the lens that causes it to become cloudy. In other cases, the inner seal that protects the headlight from water can wear out and condensation can collect inside the headlight. It is also possible that a loose electrical connection or a relay is damaged and can cause a consistent restriction of power to illuminate the bulb. It’s always best to have a professional mobile mechanic come to your location to complete a headlight not working inspection to determine what is causing this issue before deciding to make repairs.

ANSWER : A ground issue, or short, is a good place to start. There are a few ways to go about tracing down a turn signal issue. Either way you will want to use a voltmeter to trace the flow of electricity.

Since it happens when the headlights are on, the short is likely related to that circuit. Find where the two circuits come in contact with each other and test there first. This is likely from the driver controls to the headlight themselves. The issue could be in the fuse box as well.

Start with the bulb, and trace the wires. Test for available voltage along the wire. Check about every foot or so. You can use sewing pins to probe the wire, and connect the voltmeter lead to it instead of accessing the wire or doing damage.

Be sure to have a professional mechanic, such as one from YourMechanic, come to your home or business and inspect for any electrical problems and get the turn signal issues resolved.
