I have a 2001 Plymouth Neon with a factory radio that won't work. Th radio and clock both are out, but the bass and treble amber lights ar blinking. They blink regardless of if the car is started or not. Th guy at the auto parts store says it is an anti-theft device but th dealer says he hasn't heard of that. Of course he wants to charge m just to look at it. Can someone please help? BTW, the fuse i good. Thanks
