2004 Chrysler 300 possible ECM porblem.

Computer problem
2004 Chrysler 300 6 cyl Front Wheel Drive Automatic n/a miles

Hello, I was able to buy a 2004 300M Special for cheap. When I purchased the car, up front the seller told me that she left the moon roof open and it rained, most likely soaking the whole console. When you drive it, you get about 2 miles and the dash goes blank, no instruments, no lights inside, no radio, no control on the moon roof. All the fuses look brand new, could this be a ECM problem? What other things could I look at for possible problem?
