If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power it may cause the blower motor fuse to blow. The blower motor resistor or blower module gets hot as it powers the fan so often times they can burn out causing certain speeds of the fan in your car to stop working the fan can be stuck on one speed only work on high speed or not work on any settings. The best setting for diagnosis is fresh air not recirculated with the air blowing out of the center vents in the dash and the ac turned on.
