I have read loads on the heater problems, I've replaced several of the big pink 30A fuses

they keep popping, bought a new speed fan motor, checked my blades turn, but still the heater doesn't work. Someone said something about another motor for the fan (or did I read it wrong?)If so, where is it and what do I do next? Am travelling to S.France at the end of July and the dogs will die in the heat if I can't get the blower working. Thanks
