Hi, the lights on the left side of my dash cluster don't work. I changed out all the bulbs, replaced the Diode and cleaned the lamented circuit with rubbing alcohol. Did a continuity test on all the contacts from bulb to bulb but it which shows all is good, but the left half still won't work. Not sure what to check next. Please help.

Hello,

It looks like there is only one circuit that supplies power the instrument cluster lights. I would say the cluster board has gone bad maybe you can make a jumper. To be sure here is a guide to help you check the wiring with the instrument cluster wiring diagrams below to show you how the system works:
