A relay is basically a switch that can be used electrically. Electromechanical relays are the most prevalent types on the market. They perform their functions by turning on electromagnets that pull the entire set of contacts to make or break circuits. Relays also help you to perform your GMC Sierra 3500 logical car functions and inputs. If your GMC Sierra 3500 doesn't start when you activate the ignition, and if the engine light doesn't switch "ON" and "OFF", it is an indication that the main relay is not working properly.
