Hi i'm new to the site and a duramax just got rid of my 2003 cummins and now i have a 2003 drw 4x4 durmax I am happy with the truck, what a fantastic forum this is. My brake light in my dash i noticed tonight when the key was out and the door shut it was really dim and flickering like there was somthing maybe backfeeding on the circuit, I tried un plugging the switch on the master and emergency pedal still dimmly lit any help would be great thanx Ed
