Dashboard overhaul

It's not likely that all of your gauges are broken. It would be a rare event for that to happen. It's more likely that either the circuit card for the dash is damaged, or the main wire harness plug is not making good contact. Another thing to check is the voltage limiter, that's the device that drops down the voltage to the gauges from 12 volts to 5.

Change the gauges if you like, but they probably all still work. Good luck!
