Turn signals in cluster not working

[Sklptrljay]

I'm in the process of taking care of a bunch of loose ends on my truck.

I have an issue where all four of my blinkers and hazards function normally, but I have no turn signal indication on the cluster.

I have removed the bulbs and tweaked the two prongs so I know they are making contact with the (new) printed circuit. Also when I installed the cluster I ran a ground from it to a good grounding spot.

I have never messed with this, but I'm assuming since the blinkers work, the cluster turn signals would be receiving it's voltage from the flasher also, since they cycle on/off with the blinkers. I would think it's a loose connection somewhere........somewhere.

Soooo, before I start tearing into the wrong place, where do you think I should look first?
