radio workes fine at times, but most of the time the lights on radio gets bright and flashes all kinds of numbers.Volume cant be controlled , it gets as loud as it can with the volume turned all the way down,and I cant change stations either. Can someone please help? I know it must be some kind of short but where?

It could be a short, or a voltage problem.

I've heard of similar odd things happening when somebody had a corroded positive battery cable, so I'd check there first.
