I have a 2003 single cab Dodge Ram and have been trying to get the interior courtesy light to work the truck recognizes when the doors are open. I plugged in a Maximus scanner and picked up the light and gave me these codes: Headlamp Switch Circut Open, Courtesy-Dome Lamp Output Circuit Shorted or Open.
What do I do to find it? And what do I have to do? My seatbelt sign is also on and I have tracked it back to the IC too. Could be the instrument cluster?
