What Relay does for your vehicle.

A relay is simply a switch that can be used electrically. Electromechanical relays are the most common ones on the market. They do their job by making use of electromagnets that put into motion the entire set of contacts to open or close circuits. Relays also help you to perform your GMC C3500 logical car functions and inputs. If your GMC C3500 doesn't start when you activate the ignition, and if the engine light doesn't switch "ON" and "OFF", it indicates that the main relay is not working properly.
