if the blower motor is blowing on high speed only no matter what speed you select, then the blower motor resistor is burnt. also,if it's blowing through the defrost vents ONLY no matter what you select,floor,face,etc,then you have a vacuum leak,either under the dash at the controls or under the hood.when you have a vacuum leak,the blower motor defaults to the defrost mode.
