i had this problem and took it to the dealer. all they told me was that they would have to open up the car which would cost 171 dollars and that didn't include costs of repair. i switched out the fuses from 15a to 20a and everything worked fine. i would try switching out the fuses before taking it to the dealer unless your under warranty
