Recently, the stereo in my c280 has been messing up. Whenever I lane change, and hit those lane dividing bumps, the speakers only work on the left. I know that there is probably a loose wire somewhere, but where should I begin to look. Also, when the radio is playing, there is sometimes a weird type of fade. It sounds as if the radio is going in and out of the "stereo" mode--which might be related to the balance problem. The latter can be sometimes fixed with opening and shutting the driver's door, or just running over another lane dividing bump.
Where should I start?
