check your wireing for a short in it or make sure the socket isn't bad and the bulb is in tight
Possible alternator problem
Sounds like the brushes are worn down in the alternator.
If all of the lights flicker I would check for a loose or corroded ground. If only 1 light flickers then check to see if the bulb is properly plugged in to its socket, or if there is dirt, corrosion or rust causing a poor connection.
Check the oil sending unit.
It is normal. In order for you to create a spark, the coil has to open and close.
light that is not under water
Light does not go around the world. It travels in a straight line. For light to go around the world, it would have to periodically redirected using mirrors.
It shows that there is a problem with the transmission. Just like the check engine light, the overdrive light has codes that tell you what is wrong with the transmission and the various components connected with it.
The oil light is turning on BECAUSE you put in the lighter weight oil. older engines need the thicker oil.
I have an 2005 and the headlights on it will dim, and then brighten back to normal. I bought it brand new, and it has done it since I bought it. I actually took it back to the dealership, and asked them about it, and they said that Chevy knew that it would do that, but that the car would keep running, and that there was nothing that they could do about it. Hope this helps.
you have a loose connection somewhere on your vehicle check battery cables and alternator connections i have the same problem i found out what it is by the brake and gas pedals.. where the code reader goes under neith that is a black box i thinks is a power coverter i dont know yet but i unpluged it and the dome light when out but no more flicker i will up date when i found out more about this box I would think that you have a problem with the serpentine belt (also called drive belt) if it is loose it will cause the alternator not to rotate making your lights flicker and since the power steering is connected to the same belt it will also cause a low fluid pressure making your steering wheel hard to steer.
Sometimes when cornering, the overhead lights will flicker on in that model car. This is due to a flaw in the switch mechanism design, which holds the relay connection slightly apart from the bulb (when they touch the light is energized and turns on). When the car turns the centrifugal force will bring these two points together and the light turns on. To fix this, remove the plastic dome and switch cover and look for a tightening screw. If there is not a screw, you may be out of luck. If there is, tightening it should prevent this random flicker.
