The vehicle should not have been driven home with the engine overheating. It's possible that you may have now blown a head gasket and damaged the engine. The fan relay connection, if it is melted, would be due to the fan motor overheating the circuit, and the cooling fan motor, relay and connector would need to be replaced. Since you overheated the engine until it blew the head gasket and warped or cracked the cylinder head, you may now have major engine damage to go with the fan problem.
