I had a problem with my connection where the circuit board connects to the dash, as well as poor connections on the board itself. Instead of buying a new one, I built my own harness, hooked it straight to the meters and bypassed the circuit board connection. Took a little bit of work and you have to be careful when labeling your wires, but works like a champ now. If all of your meters are not working, I would start with checking your ground wire which connects at the drivers side foot area by the parking brake, and check your power lines. If I remember correctly, there are a couple different hot lines going into the meter cluster, so if nothing on it works the right place to start is probably that ground.
