I just recently got rid of my Micra due to a 15 km collision wrote it off. Prior to writing off my my Micra I experienced a blower motor issue where it stopped working. I replaced the resistor and the blower motor. I had a friend do it who works for Nissan, and purchased the resistor off of Amazon for around $32, and then bought the blower motor from Nissan for around 300 dollars. It was a little bit of a pain to get the blower motor in do to you have to go from the driver's side to replace it. You have to remove the whole pedal assembly, knock the steering column out and lift it. Even with moving all those parts out of the way it was still a tight fit.
