I can't be of any help but there is a bulb for the shifter when the lights are on. Don't know the number. Also if you use the multifunction lever dimmer it should turn on the inside dome lamp, when fully turned. Does that work? If so guess the fuse is O.K. If not maybe one fuse is out to correct both, but again not sure when looking at the U.S Owners Manual.
If you figure out what corrects these issues please post your solutions. Good Luck!
