Instrument Lights Not Working

get a test light. do you have power at both sides of the fuse when the lights should be on? check power in to the main dash cluster plug, i believe the wire is orange?? check the sockets to make sure that they ground at the circuit board. stab a small wire into the socket on the side of the bulb(to ground it) and put the bulb in place in the circuit board and take the other end and go to ground. this will ground the bulb and see if it is a ground issue or a power issue.
