The heated rear screen will be controlled by a relay somewhere, as the current needed can't be handled by the switch alone....sorry I dont know where it is though! However, if you have a multimeter, its best to check the screen for electrical continuity before you spend any more. The rear screen has 2 electrical connections - connect the multimeter to them and set it to a low resistance. If the meter shows continuity, its ok, so go for the relay. A Hyundai dealer will be able to tell you where it is.
