One lowbeam headlight out

ANSWER : The headlights are powered separately on different circuits form the body control module in the right lower instrument panel inside the car. You may need to check the connector to this module to see if the wire connection got melted there also. If the connection is melted then the connector and module will need to be replaced. If you need help diagnosing and checking these items then have a mechanic like one from YourMechanic come to you and check it out for you.

ANSWER : When you look under the back of the car and you see only one pipe out the back then you have only one muffler and a resonator. The resonator is near the back and is used for lowering the exhaust noise more and giving it a better tone. If you see two pipes out the back then you may have only one muffler but two resonators. Next time you have a service done, then ask the mechanic to see what you have since there are different models of Accords and they may have different exhaust configurations.

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 : 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.

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 : Hi there. In order to make sure that you are ordering the correct mirror to the door that your are wanting to replace, simply remove the mirror that is on your vehicle and look at it. Then go down to the nearest parts store and cross check the mirrors that have memory and the ones without memory. The difference between the two, is that the mirror will remember the settings for each time its adjusted. A regular mirror will mount on the door, however, the mirror will not self adjust and may display an engine light on the dash for a body code. If you need further assistance with your door mirrors, then seek out a professional, such as one from Your Mechanic, to help you.

ANSWER : Since your vehicle has a V shaped engine, it will likely have two catalytic converters. Since the engine is mounted transversly in the vehicle (because it is front wheel drive) there will be one converter on the front and one on the rear. If you had one replaced, it is likely the issue is coming from the opposite converter. I would recommend having your exhaust system inspected by a qualified professional who has experience in exhaust system diagnosis and repair.
