gauge circuit board

Get a new or original board. It can be repaired but likely not worth the time. It only effects the dash lights so not your real issue. Check grounds, sockets and body wiring. Lots of these issues are really in the column switch, and they are not all equal. I suggest a unit that has full length wires and plug and play connections down to the connector they have done the research for a good result. Do not go the short deal with just a cam assembly JMO!
