  1. Electrical or Alternator Problem?

    Problems and Service
    I drive a 2007 cobalt ls coupe, 5 speed. For a while now whenever my car is on, every light on the vehicle pulsates or flickers from bright to dim, literally every light. Dash, head unit, headlights, tail lights, side markers. Is this contributed to a problem with the alternator? Or something...
