Check fuses. If those are all good then check out www.batee.com They have all sorts of diagnostic DIY's on their page. They also sell parts and also provide a repair service. I sent my cluster in and he went through it for me. No more issues and it works great. He is a great guy and goes WAY out of his way to make sure you are a happy customer. If I ever have a dash issue I will only go to Bryan at Batee.com

If the gauges are working but dark (not illuminated) though the turn signals and high beam indicators are on, it's the ground between the 2 boards. Bryan at Batee fixed mine the other year, it's worked great since.

Those functions are all controlled by the switches in the center cluster. I suspect a missing ground in that area or the harness/connectors between the instrument panel and the switch panel.
