Hi Amanda fuller,
You have a loose connection somewhere and vibrations/bumps is causing it to come on or go off depending on situation. The best time to perform test is when the gauges do not work.
You would have to remove the meter cluster to perform the test.
Start by wiggling wire harness under dash to fuse box. If they start working where you wiggled, check connectors for contamination or loseness in connection.
