Hello and welcome to JustAnswer!

It sounds as if you may have a communication bus issue. The modules communicate over a wired network, if the powertrain control module isn't able to send data to the instrument cluster then the gauges will not work. A bus communication issue could be a failure in a module or a short to power or ground on either of the bus wires anywhere in the circuit.

Does the instrument cluster power up but the gauges don't work? Are warning lights staying on?
