Hi, i've got a 2007 fabia and the blower only works on number 4 so i'm guessing the resistor has failed, whilst looking for it, it would seem that its located in the top part of the heater box, if i remove the top glove box i can see it but looks like i'd need to remove either the passenger side airbag on top of the dash or the dash itself? is this correct or is there an easier way of doing it?

Thanks in advance

Yeah the airbag needs to come out to get to the resistor.
