The running lights are not working and I'm not sure where to look next. All the fuses are good and I pulled the light switch and it look fine. Any idea where to look next

 

a friend of mine had his do the same thing, I checked everything and in the end I jumpered a fuse that was not being powered up, I believe its an issue with some TIPM, cant remember what I did exactly as it was about 3yrs ago I did it. it was supposed to be a temporary fix, he never did look at fixing it properly and he drives his truck for a living (8-10hrs a day 5days a week).
I'd have to go back and see what it was I did, as the jumper wire is still there

 

i had this problem in my 03 pulled the fuse box the board inside was corroded sat with wire and soder and fixed it up, talked to some people guess you cant get a fuse box from dodge they are all on back order they just arnt making them anymore ... good luck pm if you have any other questions

 

Sometimes a fuse looks good but is not. Did you replace the fuse for the running lights or just visually inspect the one that's there?
