Have you looked at your wireing harness lately?
That would be the pump you're hearing, but it should go off with the switch.....relay or no relay!

If the relay contacts are melted together in the on position it wont matter where any of the switchs are positioned. The pump could still run on because of a melted relay. Pull the relay out and measure the resistance of the high current side. If it low you have a bad realy. IF its high you have a problem somewhere else like bad switchs or grounded wire somewhere.
