One problem related to exterior lighting has been reported for the 2003 Ford F-350. The most recently reported issues are listed below.
My dome and running board lights on my 2003 Ford f350 super duty, 4 door truck, stay on when I am driving and when the vehicle is turned off and locked. Also while driving, the dash vehicle light is red showing that all 4 doors are open. Ican be parked or moving, the lights stay on. Both my batteries drain. So I hav to carry jumper cables.
