when trying to fix a '93 dash that works when it wants to? There will be minutes at a time where it'll just flash garbled information, then show the correct display, then off...and repeat.

Gently tap the top of the dash.... does the display blink?
If so... many times it is a continuity issue within a combination of variables.

Could be the the panel itself, the harness junction behind the panel, or a broken contact behind the harness.

Been there, done that...

yeah, if I tap it or bang the steering wheel, there is activity. Sometimes it's fixes it or sometimes it makes it go off completely.

There is a large, multi-pin connector on the cluster board, and another on the center display section.

Anyway, I removed the cluster to fix a couple cluster issues. That that is when I discovered that big connector on the board itself was "frosted". (My word for the whitish powder oxidization/corrosion common to bare, electrical connections that have been exposed to air for a long time.)

Electrical contact cleaner and scrubbing removed the "frost". I repaired the tach calibration issue, and the other problems...vanished - never to return!

Disconnect battery
Remove the turn signal lever
Remove the bezel
Remove the kick panel
Remove the two big bolts holding the steering column up and lower it to the seat
Remove bolts securing the cluster
Clean the connections with contact cleaner (Radio Shack sells it or most any electronics store will have it too)
Reassemble

Entire process shouldn't take more than say a couple hours max. (based on what it took me to remove the entire board and replace the resistors related to the tach calibration.)

Good luck

First time

Good luck!
