I have a 2013 Impala and the daytime running light don’t work, but if I turn them on manually they work. What could be the issue?
My daytime running lights dont work. You can set most new vehicles lights on automatic, off or on. Mine only work in the on setting.
My car has 75000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
If the bulbs and DRL fuse have been ruled out as possible causes, the daytime running light relay or control module may be at fault. Even though the same lights are used as headlights, the DRL function is controlled by a separate module and it may have failed. The ignition switch is another possible cause. Currently, daytime running lights are not required by law in the United States. They are an added safety feature many manufacturers choose to add. If no other issues are occurring, you can leave it alone. If you choose to repair them, have a certified technician look into why the daytime running lights are not working to find and replace the exact cause.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
Check the contact point of the bulb for melting. Check the fuse if both daytime running lights are not working. If the fuse is blown, there is likely another condition with the electrical circuit, like bad sockets or a wiring issue. The ambient sensor could also be disconnected or faulty.
The Daytime Running Lights are set to turn on automatically when the engine is running and the truck is in drive. If the headlights are off or in parking mode, the Daytime Running Lights will automatically turn on. As long as all of these conditions are met, the lights should turn on.
If your daytime running lights do not come on, stay on when the car is off, or produce a burning smell, you may have to replace their module.
There`s not much of a learning curve needed here. DRLs operate all on their own. They illuminate when you engage the ignition and extinguish when the headlights activate. The driver has no real control over operating DRLs because there is no DRL on-off switch.
When you turn the key and put the ignition in the accessory position, it can drain the battery over time. Removing the DLIS fuse, when towing, removes the power to the BCM causing the ignition relay to open which stops the battery from going dead.
RTD stands for Resistance Temperature Detector. RTD`s use a specific type of metal that, depending on the resistance measured in that metal, can determine its temperature.
DRLs are lights located on the front of a vehicle that remain on whenever the engine is running. Unlike headlights, daytime running lights are fairly dim and don`t illuminate the road ahead.
Whether they`re required or not, daytime running lights are a good safety feature to have. They don`t require much power to run, and they make it easier for other drivers to see you. Just don`t rely on daytime running lights to replace your headlights.
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.
So the first thing to check is the breaker in your home`s electrical panel. If that`s not the case, you have other issues. These could include a bad light switch, a problem with the light bulb connection, loose wires in the circuit or a bad light fixture.

Okay so when I turn my lights on at night my brake lights do not work, when I don’t have my lights on they work fine.
ANSWER : Hi there. Based on your inquiry, it’s highly probable that you have a damaged light switch or some electrical fault inside the turn signal relay. However, it’s also possible that the brake switch above the brake pedal could also be the source of your problem. Due to the fact that multiple electrical components might be causing this issue, it’s a smart idea to first have a professional mobile mechanic complete a brake lights are not working inspection, so they can determine what’s causing all of these issues and recommend the right repairs.

Just replaced head gasket, changed crack sensor new plugs. The check engine light is on, but dim, the only other light that the dash is a normal battery indicator. The fuel pump is not running when switch is turned on, the power windows don’t work, it turns over but not firing. It’s like only one part of the system is working. Also the heater fans work even if the switch is off.
ANSWER : I would first look at the diagnostic trouble codes. Those codes are available because the check engine light is on. If the fuel pump is not running (momentarily) at key on, that fault alone will prevent the car from starting as there will be no fuel pressure. Pump output and pressure can be directly tested and you can also check for electrical power to the pump. To find out why the engine will not run, the recommended diagnostic is a no start diagnostic. If you request that service, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
signals, daytime running lights are not working, park brake light on dash is on steady and chime is dinging steady 4×4 wont engage
ANSWER : This is likely a brake light switch problem. I would suggest testing the brake light switch which should be located down by the brake pedal. This may also be a computer problem as well as indicated by the other lights on in the dash. I would recommend having an expert from YourMechanic come to your home to possibly replace the brake light switch and diagnose with a scanning tool which will download useful data from the truck’s computer indicating what specifically the problem may be.
All dashboard lights and tail lights do not work after driving through a lot of snow. Headlights work. And brake lights work.
ANSWER : Hello. We’ll be happy to help you. There are a few things that I recommend checking to discover why your lighting system is malfunctioning. The headlight dimmer switch should be checked. Along with the wiring harness above the right front tire behind the fender well cover. Also
the main fuse under the hood should be inspected because other people with your particular vehicle have had similar lighting issues if that fuse goes bad. It will be a great idea to check the rest of the fuses in that area too while checking the main fuse. Once the fuses are checked inside of the main fuse box then I would check the fuses inside of their interior fuse box. The interior fuse box should be located on the driver side of the dashboard near where your legs would be. If you need more assistance with repairing your vehicle please keep in mind that our organization provides Mobile Mechanics who can help you diagnose and repair your vehicle, all at competitive rates.

No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.
Dash, Tail/brake, dome, trunk, glovebox, and door lights won’t work, dash doing weird things.
ANSWER : Hi there. Sure would appear a lot is going on electrically all at once. This could be, a problem in the PDC (power distribution center). The PDC is typically located under the hood and contains numerous fuses and relays. I don’t believe any one fuse will resolve all of the electrical issues. There is a possibility, it is not a power supply issue. It may be, the result of a poor electrical ground common to the inoperative components. Proper circuit testing should be performed. This would confirm the cause of multiple electrical failures. I recommend having your vehicle’s electrical problems be diagnosed and repaired by a certified technician, such as one from YourMechanic.
Electrical problems after upgrades
ANSWER : Hi there. From the description you have provided, all of your vehicle’s electrical problems began with the "upgrades". Unfortunately this could be a can of worms to repair. Assuming, you had a qualified technician install the vehicle’s radio and lighting upgrades and all was fine after the installations. This would lead me to believe your vehicle has several problems. The first place to look would be fuse(s) for the inoperative components. Next, to look for shorts to power the components staying on. If you can find the problem yourself, I recommend having your vehicle’s electrical problems diagnosed and repaired by a certified technician, like one from YourMechanic.
