OK. So after a night out I left my windows rolled down before a bad storm. Everything on the passanger side got completely soaked. Now the car won't start(does absolutely nothing as if the battery were gone), baterry is fine, lights on my dash aren't turning on, the cont-passive belt module makes a clicking noise, radio doesn't turn on,and interior lights are dim. Here's what gets me though, this happened about a week ago, wouldn't start. Yesterday, while I was at an Ultimate tournament, my father was able to just start it up, none of these symptoms, several times, even took it to the grocery store. But today when I went to start it up, nothing.

Same as before.
Does anybody have any ideas what may me going on that I can look for? I'm still " new" with dealing with electrical stuff so any advice would be more than helpful.
