Headlight stuck

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 : Hi there. Based on what you have written above, it is highly probable that the inner linkage has come loose or there is an obstruction within the inner gear set that is causing your problem. Unfortunately, this typically requires dropping the transmission and repair or inspection from the inside. This is not a service our mobile mechanics are equipped to offer, so your best bet is to contact a local transmission specialist for assistance.

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 : Hi there. If the vehicle has sat for an extended period of time, it is likely that multiple components; internal and external have ’frozen’ or have lost lubricity and are literally stuck. The clutch and transmission specifically can be negatively impacted due to lack of motion since it’s a hydraulic system, meaning it depends on consistent flow of fluid to maintain pressure in the system to work correctly. The brake pedal is also a hydraulic system – which is most likely why you’re having issues with this system. In regards to the helicopter sound, it is likely an exhaust manifold or exhaust pipe connection below the manifold that has cracked. However, since the Mitsubishi mechanics that apparently use stock exhaust manifolds on their "three times HP engines" said that’s impossible, maybe it’s best to take your car to them and have them put their skills to work to resolve your cars issues. To be honest, fixing the clutch, brake pedal and other systems that are stuck is going to be difficult and probably very expensive, so you might want to contact some other mechanics to get some estimates about repair costs before you get too deep into this project. Best of luck.

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 : 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 : Your vehicle is probably equipped with daytime running lights, whereas the other car you saw was not. On your vehicle, these lights will stay illuminated regardless of whether the exterior light switch is in the on or off position. There is no way for the driver to disable this system. In theory, a mechanic could re-wire your system to prevent the lights from turning on, but that would be costly and may be against the law in some states. My advice is to just accept the daytime running lights for what they are.

ANSWER : It sounds like you have a rubbed through wiring harness or two. All the components you mentioned are switched on the ground side. That means if there is a short to ground on the switch side before the relay, then the light will turn on. This would lead me to think that there is a rubbed through harness in the steering column. This will not blow a fuse though.

The light or horn will simply turn on without you moving the switch. The fuse for the taillights and dash lights is a different concern. A short to ground on the positive side, after the relay will blow a fuse. It will only blow the fuse when it is switched on. This could mean a short in any positive wire in the taillight circuit. There are a lot. Every switch that illuminates when you turn your parking lights on could be shorted. Any taillight or parking light circuit, too.

Here are some tips. There is only one way to find this type of problem – it will have to be visually traced. Follow the harnesses with your eyes and look for damage. Use the clues that the car is giving you to narrow your search. The wires will need to repaired after the problem is found. If you need help having this diagnosed and repaired, a certified technician from YourMechanic can inspect your electrical system and let you know what fixes need to be performed.
