OK so I have a 2011 f350, the driving running lights have always worked while my headlamp switch was in auto during the day. But here recently the running lights won't turn on during the day under auto. They work at night, and work just fine when exiting and entering vehicle. I know to make sure the switch is in auto and to make sure I'm in gear. And not in park. I double checked to ensure parking brake wasn't barely tapped. So I'm lost. Nothing has changed. If anyone could help I would greatly appreciate it.
