It sounds like either a connector is loose or the circuit board for the instrument panel may be damaged and need replacement. Remove the trim panel by taking out screws and carefully pulling out. Then gauges will come out after removing screws as well. Then you have to pull on it some to get your hand behind it and dis-connect electrical connectors. Then the assembly should come out easily. You will be able to tell if a connector is not tight as you will have to grab a connector release the dis-connect it. Feel around the connector and you will be able to tell where to push the tab in to dis-connect it.
