It sounds like you might have an issue with a live wire. Always check your grounds to make sure that they're intact, then follow any common power sources for your lights, locks, etc. Check around your fuse box as well and make sure that there aren't any water leaks coming in from under the hood, thru the slits in the fender, whatever. If you know how to use a multimeter then check the output of all those leads giving you a problem. Good luck.
