I’ve had the same problem, 4 or 5 times at this point. Every time I have my mechanic plug in his tool into the OBDII port. I think he just clears the codes that come up and they work again. From what I understand, they made these trucks to where fuses don’t protect most of these circuits. Instead, they made the computer in charge of the fuses job, shutting off the circuit when it detects a problem. I’ve also read elsewhere that replacing the TIPM would fix this, but that’s an expensive fix. Anyone that knows anymore please help, I’m tired of it being Friday night and no place is open so then I don’t have lights for the weekend. This effectively disabled my truck!
