Hey, I have a blow bulb in my auto climate controls. The bulb that illuminates the red arrow button and the "AUTO" and "ECON" buttons is no longer functioning. I have never had good luck at replacing lights in tricky areas like dashboards, I can never get the dash back together properly. Has anyone changed this bulb before? What exactly does this involve and what part # is needed? I woudl appreceiate any advice fellow Max lovers can offer.
