ok, I know all the problems with Bose stereos. I recently purchased a used 94 Maxima with the factory installed stereo. Of course the display doesn't light. However, after reading through all the posts here, I haven't seen anything that matches my really weird problem. I've got the AM/FM cassette CD combo but only the AM radio emits sound. I can hear the CD or cassette whirring, but nothing comes out of the speakers. Same with FM. On top of that, the AM only works when I turn on the headlights! Is it possible the previous owner had a different system in that really screwed with the wiring? How do I try to fix this?
