The fuel temp oil module on the cluster is the brain and a few weeks ago the illumination lights went. When I pulled it I found a broken printed circuit path which I tried to fix with a jumper.
This worked fine, for a week, Then another path went, which I fixed with another jumper..all these paths come from the main plug which supplies the module with info...then another path went
The trouble is is that there are different grounding points in the cluster, I tried running my cluster illumination lights off of a jury rigged harness to the center console and now my cluster flashers dont illuminate (they still flash) because they are at a different ground level...
Anybody have experience in this area or matter?
Once I even fixed the clock by replacing a burned out resistor/diode , that was real subminature wizardy, but now I am stumped....

Go to the junkyard and get a replacment, your's is cracked.

Be carefull when installing that you don't get something behind the circuit board flexing it.
