im not sure if this is the right section but here we go, I have a 2005 explorer xlt I just purchased recently. for some reason the dome light stays on when I shut the doors and says door ajar on the dash. unless I turn the switch all the way down. when I get in my truck the light stays on. if I turn the interior light switch all the way down it goes off, then I have to turn the switch back on to light up my dash. if the interior switch is off when I get in and shut the doors the interior light wont come on and it will not say door ajar. I am not really sure where to start. any input is appreciated thanks
