Hi Shun

Need to know some more info.  Need to get tot he blower and check for power.  If you have both power and ground then your blower is no good, replace it.  If you have power and no ground then replace your blower resistor.  If you have ground and no power then you must check wiring if your fuses are good.  let me know
