Sounds like a plugged evaporator core. The blower motor in located under the dash on the passenger side, behind the glove box. Some models have a trim molding which will unbolt for access. Once you have removed the blower motor, look inside the duct work and see if dirt, paper, ect has plugged the evaporator core. Sometimes a small vacuum cleaner will be able to **** out the debris.
