2004 Chrysler Pacifica Not Starting At all
 

ok so my wife drove the Pacifica through a big puddle after which the lights on the dash started flickering but she was able to still drive it home and drive it another time later that evening. The next morning she turned the key, lights came on and went completely dead after turning the key all the way. Now there is absolutely no sound or light when turning the key. Any ideas?

Meanwhile as the Pacifica sat, the battery drains completely. Wondering if its a ground wire?
