20`8 Mazda CX5 AC fan works one day and then it wont work.Ive check all Fuses all good check blower it works
if you have less than 36k miles you are still under warranty and should bring it to the dealer. if not it could be a blower motor going bad, a bad blower motor resistor or the control module or circuit board behind your fan speed control knob. I am not familiar with your vehicle but those are my thoughts.
a good repair shop should be able to tell you and fix it.
