I know i shouldn't post on this forum this question but the other forum i posted on isnt as active as this one. U have a 2006 chevy cobalt and my passanger door won't lock but the black lock thing goes up and down but you can still open the door with it down does anyone know whats wrong or how to fix. It? Sorry that this doesn't have to do with car audio i just know theres a lot of car experts on here. Thank you
