To test a power steering relay, first locate the relay in the vehicle's fuse box or relay panel. Use a multimeter to check for continuity by removing the relay and testing the terminals; there should be continuity when the relay is energized. You can also swap the relay with a known good one to see if the power steering system starts functioning. If the relay fails the continuity test or the swap does not resolve the issue, it may need to be replaced.
