heater and ac blower

As "Hemicuda" has said the blower motor is located at the passenger footwell area (it is relatively easy to replace .6h to 1hour labor), the blower motor has a blower motor resistor that may fail or allow the heater blower to operate at only one speed (to replace this the glove box must be removed to gain access). Before replacing parts ensure that all fuses are OK.

Should be located against the firewall under the hood on the passenger side, Kind of a square box with a snail looking thing with wires coming out of it, that would be the fan motor but I see a blower motor resistor available for your car also.Should be changed by a mechanic.
