Re: Interior lights come on randomly while driving
Yes, the door switches are inside the door latches. If a door switch gives a momentary door open signal, the BCM will switch on the interior lights and keep them on for a preset time. If this momentary signal is very short, the EVIC will not show a door open, but the BCM will still switch the lights on. Finding the faulty switch is not that easy, you probably will have to disconnect one at a time and drive to see if the problem is fixed. I would start with the door which is used the most. The problem can also be a shaved wire isolation, which makes contact to ground once in a while.
