The cigarette lighter in the cab works but not the 3 in the sleeper berth. Can't figure out what fuse it is. 2019 International LT.
I drive the same exact truck. Check your fuse box in the side door on driver's side. I believe the fuse for those is in that fuse box.
Grab a test light and probe both terminals on each fuse. Any fuse that only lights up one side. Is blown. You might find other fuses that are blown also..that you're not aware of. Good idea to check em all and it's an easy process without having to pull em all out.
