My tail lights were out. So were the lights for speed, gas, and temp gauges. I was told those are both on the same fuse so it's no coincidence they both are out at the same time. I replaced the only fuse behind my coin drawer in my 2001 Toyota Sienna CE (250k miles) that was blown and the tail lights came back on. The dashboard gauges lights did not. (Incidentally, ABS, CEL, door-is-open, O/D OFF, CRUISE lights never had an issue even before I changed the fuse. It was just those three gauges that I couldn't see at night.) Does that mean that the fuse for the tail lights isn't also connected to the gauge lights or does that mean that whatever blew the fuse took out the lightbulbs for the gauges as well?
All cars are different.. a lot of manufacturers put tail lamps on the same fuse as dash lights just to indicate a problem otherwise if your tail lights were out you would never know it unless someone told you
