We need a little more context. Does the vehicle still start and drive fine? Did the gauges suddenly stop working or did things seem amiss before they stopped working altogether?

Did you check the fuses in the interior fuse panel? Your turn signal chime is produced by the front left speaker so whatever the issue is is affecting more than the gauge cluster. Without knowing anything else, I suspect a fuse related to the BCM is blown or you have an electrical system issue. I would have your battery and alternator checked if the fuses are OK. Computers do weird things when they don't get the power they need.
