I own a 2005 Chevy Cobalt. I bought in 2005. Many issues started and no one seems to know what it is. The driver seat warmer doesn't work passenger side does. Rear windows won't roll down (power windows). I've had to replace turn signals, brake lights and head lamps many times, now the turn signal arm won't return automatically when I'm finished with a turn. To use the left signal the arm is difficult to get into place almost like it's not getting into the slot correctly. There are no bells that chime in the car ex: key left in the ignition, turn signal sound or when low on gas. Now this morning noticed my rear defogger isn't working. I've taken it many times to the dealership and of course they have no clue and I've also taken to independent mechanics and they also have no clue. A gentleman at Auto Zone said that it sounds like a Body Control Module. The radio and speakers works great. With these going out one at a time it's making scared to drive my car, could someone please help! I am thankful that I've not issues as others.
