This could be the heater switch which is below the middle of the windscreen in the engine bay, very possibly the switch has failed meaning it wont stop the flow of coolant to the heater matrix and it blows hot all the time and the switch could be causing the fuse to blow. the switch is relatively cheap I just had the same problem and the pipes on the switch were broken and the floor of the car was damp with coolant switch costs £11 on flee bay.
