2005 Jeep Wrangler instrument cluster

I just had the same problem, the instrument cluster powers the dome light and the door ajar lights. You have to got to the 100 wire connecter under left side, drivers side and find if you have power to the blue/green wire which goes to the C1 connecter behind the instrument cluster. If you have power there chances are the circuit board is bad, go to a wreckers as they are quite expensive. Additionally if no power at the 100 wire connecter the instrument cluster is fed through the rear window defogger relay which is located in the fuse box on the right side of the engine compartment.
Good luck
