Hey guys. I've had my 20005 2500 cummins for about 3 months now, and since it's gotten cold I've had a problem in the morning that the lights will dim for a minute or two, and then brighten up. It will do this for a few minutes probably about 10 minutes. Doesn't matter if I'm driving or if I'm sitting. Anyone have any idea what this could possibly be?

 

do a search for grid heater. That should help you out alot

It worried me too the first time I saw it. I was disappointed when I traded the 96 for an 06 and it did the SAME THING. Oh well...dont mess with what isnt broken, eh?
