Interior lights will not shut off.
I have a great 1986 Chrysler Fifth Avenue that I enjoy driving. Occasionally, when I shut off and leave the car, the interior light will not shut off after closing the door. I have been watching this erratic behavior for 2 years now. Many times I have returned to the car just to find a dead battery. Today I found the lights staying on gain. I left the car alone and returned 15 minutes later to find the light still on. I pulled the fuse for the interior lights and reinstalled it. I closed the door and the lights went out. Is there a circuit board that controls the interior lights? If so, where is the circuit board and can I replace it? Thanks in advance to anyone that can help, John
