So if those 2 screws are not clean and are not making good contact with the metal trace in your new printed circuit, you could have a lack of proper ground to the cluster lights other than the far right one. Don't know if that is the whole problem, though. Here is a diagram of the cluster printed circuit.

This is what I'm thinking too. The problem arose after the truck sat for a while, and with the drastic temperature change from spring to summer, it probably has oxidation build up, causing the break in contact when dry. Thanks to all for the insights
