Nissan Patrol 4x4 (Africa)

just a random observation I made this morning, I also get the annoying flickering light and this morning decided to start diagnosing by unplug the left barn door switch and see if it solves the problem but noted that the roof lights remained on BUT when I closed the right barn door the light went off

thus there must a switch on one of the right barn door latches and maybe this is the culprit giving some of us the run around ....

I have also tried to build up the left barn door sensor but still I had the flickering light. Would love to hear if anyone has a conclusive answer to which door is the problem?
