First of all I'd like to say hello as I am new to this forum. I have a 2008 charger se with some issues. First of all, it constantly says I have a door open when I clearly have all my doors closed. Because it says I have a door open I have to keep my gauges turned down at night so the dome lights aren't on. Any ideas? Secondly, my service engine light is on. I had the computer checked and they said my gas cap was bad. I replaced it and had the codes reset but the light came on again for the same reason. I've checked it numerous times to make sure its on there correctly and tightly. Any help would be greatly appreciated!
