If a digital display is not lighting up and others are, then you need a new instrument cluster*.
If it is lighting up, but giving the wrong information, then I would check the wire providing the information to that gauge using a multimeter and a factory service manual set (which would give troubleshooting instructions). There could be a problem with the wiring, a connector, or the sensor.
*If you know how to work on electronic circuit boards, sometimes instrument clusters might have a loose solder connection or broken trace. Might take a peek and do a few checks with a multimeter.

I have a spair cluster that i put in.same 2 gauges not workin
Well then you would need a factory wiring diagram which would be a part of a factory service manual set.
Then look at the diagram and see how these work. Where they get their power from.
Then test with a multimeter.
Also don't assume it is not a problem with the instrument cluster (because of the swap having the same problem). I've seen some products that have a part which tends to fail and all or most older parts have the same problem.
But you don't know for sure until you can look at a wiring diagram and see how everything works.
