Nissan LEAF PTC heater replacement: 2014 Gen2 AZE0 RHD

I struggled to find much information about how to change a right-hand-drive AZE0 PTC heater, the procedure is different to left-hand-drive models. The Gen2 AZE0 Acenta has both a heat pump ant PTC heater, the PTC is used to provide instant powerful heat, while the heat pump is used to efficiently maintain cabin temperature. Only the PTC heater is used during cabin pre-heating and the heat pump does not function very well in sub-zero temperatures, therefore a faulty PTC heater causes significant issues when trying to heat and defrost the car in winter.
