So the speedometer doesn't work.
That's a good clue. The power for the warning lights and gauges comes through the speedometer connector, that L-shaped plug. It is the red/black wire; comes right from the ignition switch.
With the cluster out, check with your test light (something that draws a little more current than a multimeter) for power on that red/black wire at the pins. Look in the end of this card-edge connector to be sure the connector has enough tension to squeeze on the circuit board fingers. You can open it up and re-tension it if necessary.
On the cluster itself, make sure someone didn't have the speedometer out for "re-calibrating the milage" or fixing the odometer gear, and then didn't get it properly seated in its connectors. You'll have to unscrew it.
Don't be tempted to add solder to the PC fingers to improve the connection at the L-shaped plug. This is a solution which has about a 90-day life because of the soft metal. It will actually make things worse, but some will have to learn that by experience.
