Why are my headlights still on when car is off?
For instance, some cars are designed so that if the engine is shut off while the headlights are on, they will remain on for a specific amount of time. Other cars have daytime running lights, which is essentially just a system that automatically turns the headlights on—but doesn’t affect the dash lights—during the day.
Why are my inside car lights not turning off?
The likely cause of a dome light not turning off is either the dashboard light control knob being activated accidentally or a broken door switch. You can remove the wire from the door switch, if you are able to access the backside of the switch. The wire pulls off of the switch easily.
Why does my car keep running after I Turn Off the ignition?
Running-on is when the engine continues to turn after you’ve switched off the ignition because the fuel /air mixture is being ignited by a hot-spot in the combustion chamber.
What does it mean when your car won’t turn off?
It can be very frustrating when it doesn’t. If the engine continues to run just as before you turned it off – as if you hadn’t turned it off at all – your ignition and fuel system are not shutting down. In that case, your car has an electrical problem that needs to be addressed.
What causes a car to run on without a spark?
The problem can be so bad that the engine runs on for a minute or more if left alone. Running-on occurs when the fuel/air mixture in the cylinders ignites without a spark. This is known as the dieselling effect because it is caused by the fuel igniting spontaneously in the combustion chambers, which is what occurs (deliberately) in a diesel engine.
Why is the Check Engine light not working?
If the ECU can’t get a clear signal, the engine may fail to start or die immediately after starting. Your ECU should throw a check engine light if there is no signal from the crankshaft or camshaft position sensors. Get this code read if you can, as it may tell you the exact wire that is causing the issue.
Why do headlights stay on after the ignition is shut off?
If so, try this: Turn the lights off before shutting off the ignition. If your lamps are staying on permanently after: 1) ignition shut-off, and then 2) light switch shut off, suspect something in the headlamp-off-delay feature. (This assumes that your vehicle is equipped with this feature.) Thank you for reporting this comment. Undo

Why do my headlights come on in the middle of the night?
My headlights mysteriously power on in the middle of the night without any key in the ignition or it started and drains my battery about every night almost for a week now. I’m not sure what is going on. Is it a fuse or relay? Is it my turn signal switch and corrosion?? Help please. Tina Daniels My car has 167834 miles.
