Re-solder the connections inside the warning light cluster. It is very common for the cold solder joints to fail. Focus on the joints where the wiring harness pins connect to the circuit board and other places that look like they have lost the connection. Also, remove the old solder before re-soldering the joint. If you just reheat the old solder, the problem will likely come back and you'll have to do it all over again.

No problem. Be careful removing the warning light surround if it is still in one piece. Good info from Aaroncake, a forum moderator, about this procedure and lots of other RX7 related knowledge. http://aaroncake.net/RX-7/tech1.htm
