My back drivers side brake light doesnt work and also my front drivers side blinker does not work. All lights have been changed but still do not work. Also my stereo doesnt work all the time. It only works if my blinkers make noise if i turn them on if there is no noise when the blinkers are on then the stereo does not work. Does anyone have any suggestions as to what could be causing these issues? Could it be a wiering problem?
