If you turn turn signal on, four way switch makes odd vibrating noise but no signals work.

It sounds like a bad flasher. Take a look at this and let me know if it helps.

Possibly. However, since things are not turning off, it sounds like maybe a short to power. Check the wiring in and around the fuse block under the hood. Also, if you have not replaced the four way switch, that could be the problem.
