I keep getting a noise that sounds like the turn signal or 4 way flasher is on when they aren't. The noise sounds as though it is coming from behind the radio. I have been told this is a common problem for this auto, but nobody seems to know what is causing it or how to fix the problem. It clicks very often and is very annoying to me and I'm afraid if it is something major, it may burn something out or even worse, start a fire. Thanks for any help given.
