I have a 2003 Excursion and for the last 1-2 years the lights on the running boards and sometimes the cargo light stay on for up to 30 minutes after I turn off the key. Had it checked a couple times and no one can seem to tell me what's wrong or how to fix it. The door ajar light also stays on but not all the time. Anyone have a similiar experience or any remedies? Thanks, Jason
