The relay acts as an electrical switch. When the vehicle's control circuit calls for cooling, it sends power to the fan motor. If a failed relay or a damaged connector is why your cooling fan isn't running as it should, this kit replaces both parts. Diagnose the cooling system first, because fan and temperature problems can have other causes.
