Don't take it to the stealer. I have a feeling it's a fuse. I would start by checking all the fuses. They have 12 volt testers at auto parts shop for 10 or 20 dollars... surest way to check them. Also just look and see if any are burnt.
In my case the mechanic just said "open circuit" was the problem. I didn't talk to him but they made it sound like it was a burned wire.
