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.
