It sounds like the battery is flat, this could be because the alternator has not charged it or something has drained the battery or the battery is faulty! What lights are flickering? We're any dash lights on prior to you not being able to start the car?

I would check your fuse board for a loose fuse or wire to it from the battery as sometimes vibration loosens terminals eric

check fuse panel first for blown fuse,second check your daytime running lights come on without flickering. if problem persists- all these are affected by headlight switch- controls interior lighting and headlamps and daytime driving lights

Sounds more like you have a grounding problem. Check all the ground wires from body to the chassis and the large one that goes from the battery to the engine. Look for faulty cables or bad or rusty connections. You can even add a couple of new ground wires to make sure that is not the problem.

interior control module.

It is a safety feature so you cant run the battery down.

the dimmer switch may be going bad--at night do you may see a change in the dash lighting as well --maybe even going off all together---sometimes adjusting the dimmer switch may give a temporary fix -the switch controls dash and dome lights and is a part that does wear with use

How many volts do you have when before you try to start your car? It seems as if your battery is not holding a charge, being that you are getting enough volts to charge the battery. I would check the fluid level inside the battery and fill it up with distilled water if needed. Also it wouldn't hurt to clean the battery terminals and wire connectors. Also make sure that the connection is at the top of the terminal and not the bottom (nearest the battery casing).

Have any of you guys checked the battery to see if it is charged enough and holding a charge. To do this check you need to use a voltage tester and the reading should be around 12.4 volts. If not make sure the battery is full with distilled water and then charge the battery.

Next you need to immediatly check to see if the alternator is charging the system adequately. If not replace it before you kill the battery again.

Also clean the terminals on the battery and on the connectors even if they don't look like they need it.

If the battery still dies you may need to replace the battery because it lost its ability to keep an adequate charge.
