Recently my Concorde has started to have issues with the interior lights randomly blinking on and off while driving. I used to think it was a loose wire or something that was getting wiggled when I would hit a bump, but now its doing it while not moving or parked (car still running). I also thought it could be something to do with an open door sensor but that notification light does not come on on my dash. Also, if relevant, my trunk light has stopped working. My dash lights still work perfectly and, as far as I can tell, my headlights are fine too. My question is, what could this possible be, as how do I fix it? It's driving me nuts.

 

Interior lights : Roll the dimmer switch full up/full down a few times. Roll up to the "stop" and back off a bit. Usually solves what is known as "the light show"
There was a TSB on this issue.
Trunk light is usually a break in the harness from the trunk to the lid on the left side.
