Sounds like a short somewhere. They dont all share a common circuit which is puzzling, unless a connector has come loose somewhere that they all share.

Been there Done that

I had the same problem a few months ago. Took 2 days in the shop to trace it down to a dead short in the system. May as well take it on in.

LOL, I just realized, I've experienced most of the problems people post about here. I guess that helps prove the point that my 03 has been trouble filled.

I had the exact same problem with the strobing of the lights and radio, etc. It turned out that the ground cable from the battery to the frame was defective. Changed the cable, and the problem never came back.
