My car runs but the gauges inside of the dash do not work?

Hello,

If none of the gauge is functioning, then the issue could be a faulty gauge cluster.
It can also be due to a wiring issue.
Do the gauges light up?

In order to figure out what could be the issue you will have to access the back of the gauge cluster and check for any wiring issues. Look for any pulled out pins or burnt connectors.

Check for power to the plug and make sure you are getting prover voltage.

It is also possible to have burn circuit boards of the gauge cluster.

I have attached the wiring schematic below.

Please let me know if you have any questions.
Thank you.
