Windows, locks, and ignition all failed

[kichi]

I let my Boxster sit in the driveway for a few months without starting it under a roof that poured water all over it.

I Jacked up the car and replaced the Axel's and when I went to start it, it would not start, the windows acted like they were haunted and would go up and down on their own anytime I hit the up or down buttons and every time I went to unlock the car, a 3 second long strange noise comes from the drivers side door. I also go to turn the key to start it and nothing happens. I do this about 10 times and if I hold the key in the final position to get it started it finally starts. So I drove it to the gas station and leaving after it was warmed up I punched it and a plume of white smoke came out the back. I am replacing the Air/Oil separator, but what do you think the electrical issues are please? How could 3 electrical issues all happen at the same time? I checked the fuses and relays and it is not that.

Thanks,
Chris
