Bought a project car and trying to fix odometer. Checked fuses and they are good and the bulbs are good. I cleaned the connection and still no lights.

Hi,

Do you have the printed circuit board out of the dash? Have you checked for bad solder joints? Have you confirmed power to the circuit board for the affected lights? Is there power to the sockets of you use a test light? If there is no power at the connection, have you tried back tracking to see if there are any wiring issues? Are the odometer lights the only ones affected?

Let me know. Because of the year, my schematics are basically nonexistent. I'm trying to think of things which can cause the problem.

Let me know.
