Mic - Is that a TSB?
I just went out to my '02 DuraMax 2500HD CC and the tail lights are stuck on. I unplugged the controller for my trailer and no change. The right blinker will knock out the cyclops and tail running lights, but then the right directional is stuck on and not blinking. The left directional works normally and has no effect on the lights.
The lights and cyclops are now stuck on. I pulled the fuses marked brakes and that had no effect. I am at my wits end!!! Any idea what this is?
