In this video I demonstrate how to remove and reinstall the cabin air filters in a BL Mazda 3 (2009 to 2013). If your trim level is Neo or Maxx, then I also show you where the Variable Fan Speed Resistor (VFSR) is. If your trim level is higher than that, then the VFSR is on the other side of the HVAC assembly.
