Try pushing the tone button, then fader, then press and hold the menu/select button down until the number changes to 0. That will reset the fader to center.
To adjust it to a different number just rotate the menu knob and push the button once to set.
Does this vehicle have the rear seat DVD infotainment option? If so that option has rear seat headphones that use their own controls. If you hold the stereos power button on for 3 seconds it will turn off the rear option and enable the "normal" speakers.
