I have a factory CD radio and once you turn off the engine the lights come on and radio will stay on for a period of time. But as soon as you open a door the radio is supposed to cut off. This works just fine with every door except the driver door. It will stay on and continue to stay on even after it's locked and I'm walking away. If any other door is open then it turns off just like its supposed to. I don't understand whats going on. And the weirdest part is that it was only doing this like every once and a while, now its every time...Any suggestions?
