I have a 2008 2500 and I can't for the life of me get my cab lights to work can't find a fuse all lights work besides my interior lights everything else works as the should any help would be much appreciated

 

I believe your cab lights are on same fuse as your dome light. The fuse should be in the box at the driver's feet.
Your manual would have the fuse listed, or do a search if you don't have your manual.
This would be a good time to learn how to check fuses with a multimeter/DVOM if you are not already familiar.

 

Cab over lights and the dome lights on the same fuse? The problem is there isn't a cab fuse box everything is under the hood unless there's something I don't know about I searched the cab up and down for a extra fuse box
