Dead Battery Car Light

The check engine light flashes or stays on constantly.

Dead battery car light.

Now we re not talking about that dead battery that you get when the dome light was left on or the car hasn t been driven in a month. Why your car battery died faster than expected there are several things that may shorten the life of your car battery. Of all the signs your car battery is dead this one is a little different. In this situation you might think you need to replace your battery but that s probably not the case at all.

But you may get lucky and discover that it s only your car battery that needs replacement. Visit your local autozone store for a free diagnosis. As a result your car s computer which is responsible for reporting error codes is also receiving low voltage. If the battery is very weak the dome light may appear dim.

If you re having to boost your car after it s been parked overnight but not again while you use it for the day your battery probably isn t the problem. If the battery is low you will see a weak door light but if the battery is dead the door lights will not come on. No dome light when opening the door or no door chime with keys inserted. If you replace the battery and the problem persists the problem may be with the door wiring.

So what should you do. A dying fading car battery means low voltage. An error code will be generated which will in turn trigger the check engine light or even the battery charge warning light to display. Usually a jump start booster pack or battery charger is all that s necessary to revive the car battery and get the car back on the road but the damage has already been done.
