it's either a fuse or it's a bad blower motor, it could be a bad blower motor resistor but usually you'll get either high or low only, so if you have nothing on any speed, high low etc, and all the fuses are ok chances are it's your blower motor.

there are 3 fuse boxes called S.A.M.s and m.b. doesn,t want people changiong fuses. on the driver's side of the dashboard there is aplastic cover. if you open the door wide you will see it take a flathead screwdriver and pry it off. the diagram is located in the fuse box. look carefully and you will se it folded into a square on one of the sides of the fuse box. just replace the fuse with the right rating

If you have the hood up stand outside while someone activates your air off and on and see if the clutch on the compressor goes on and off while they activate the switch. If that isn't it the it could be improperly charged system or your climate control door that opens and closes for hot or air is not working properly and only stays on heat.

You have clean the blower unit , may be its dirty then . and then check the blower resistor unit for malfunction.
