I have an '06 3500 that I purchased new, that now has 137,xxx miles on it. Since '09 it is on it's third tipm due to the left headlite failing. Dealer blamed it on bright box, so I disconnected it after first replacement. Failed again and again they blamed it on the brite box and I told them it was disconnected, so third one has been in for around a year, and now I have no trailer running lights. I found a 30 amp fuse blown, replaced it, but still no trailer running lights! Is there something else that can cause this, or is is the tipm again? I have a buddy that had an '03 and he says he had to have the dealer "reset" his tipm before. Any truth to this? Thanks for any and all advice!
