Hmm, I had taken my cluster out and sent it off as I went through the FSM
I was ready to remove the wiring harness and thought for all that trouble a quick call to Gordon was worth the $50
Perhaps you should try a call before sending out the cluster, if you're at that stage?

I had very similar symptoms with my '91, the only difference was that sometimes half of the segmets disappeared like that:
You can see, that there is also km/h and MPG readings lit at the same time, which should be impossible (one is metric and the other isn't). Reason for this behaviour was, that there was a minor crack in the top of the lcd panel

I replaced the whole thing with a used IC from a vendor here in Finland (I think that was from '90). Then I bought a used IC from a '93 (because of the 'hyphens' in the background of the scales of the gauges), but the lcd and tachometer were 'kaput'. So I took the oil pressure, coolant temp etc. gauges put them into the other IC...
Collection:
Trying the '93 IC (no flickering, just erratic segments)
The final solution in its place:
