Hi I just bought my first cobalt yesterday it is a 2008 chevy cobalt LT. The front windows which are power windows work, however the back windows do not work. I have checked the fuses and they all seem in good condition. I have also put the key in the ignition and turn it before the motor turns over. I looked at the dome light while pressing the rear window button and the light did not dim. I am not sure if I am missing a child safety lock or something electrical. Please help!!
