Re: Problem with courtesy lights
Check underneath the door seal plates/trim to see if the wires have rubbed through. I have had it happen on a couple of trucks. The bulbs have power all the time. When the door is open it closes the ground circuit. If the ground wire has rubbed through and is touching a body panel it will complete the circuit causing it to stay on. With all the dirt that comes off of shoes and falls in the floor pan, it acts as sandpaper to the wires and over time they will fray. Good luck.
