Interior light flashing

The middle interior light for the front and back turns on and off by itself all the time and the door ajar light itsnt light on the dash so I have no idea what it is but it's driving my CRAZY!!!!! Lol I took it all apart and it's a circuit board so it's not like I can even fix a broken wire, I was just wondering if anyone had the same problem and know the fix.? I'm prob going to have to buy a hole new assembly unfortunately.... Thanks

Is the problem affected by the switches? I know they're probably bus switches anyway but playing around with the left/right on/off function and observing the result may help narrow down where the problem is occurring.
