911, what fuse for dash lights?

What do you mean by "all lights?"

IF SOME of the dash lights work that operate of the dash dimmer, then the circuit is OK and you have lamp or socket problems

By the way, the dash light fuse gets it's power from the headlight switch (dash dimmer) WHICH GETS ITS POWER from the tail light fuse. So if the tail fuse is blown or not making connection, the dash lights won't work, either
