Good afternoon,

It sounds like you have low battery voltage if you have to jump it. I would load test the battery to see if your battery is any good.

I would also check the battery cables and clean them.

Then I would check the charging system if you get it started.

Let me know the results.

Okay, check the diagrams I posted. The instrument cluster is fed from 2 fuses. Check the fuses with a test light to be sure there is power on both sides.

If they are good and the cluster still does not work, then the cluster is the issue and must be removed and sent out for repair.
