Has anyone experienced a bad contact in their turnsignal/headlight switch on the steering console? I cannot dim the interior lights and it will flicker between full dim and full bright depending on how I push the stick. I think it is a bad contact within the signal lever, but before I pursue that, I wanted to see if anyone else has experienced the same phenomenon. I have done some custom wiring, but I can't see it causing such an intermittent condition. FYI, I have the 2012 JKU Manual.
