Hi mike:

the blower motor is under the glove box on the right side of the dash on the bootom of the heater box. It attached to the heatre box by 3 screws it's not a bad job. BUT it may not be the blower motor. use a 12 Volt test light and test across the 2 wires going to the motor with the key in the run position and the blower motor on hi setting the test light should be BRIGHT if it is then blower motor is bad if it doesn't light up chance are it needs a blower motor control module which in right next to the blower motor it has 1 connetor on it.. Those would go bad more so then the blower motor. Also make sure there are no blown fuses in the fuse box for the HVAC and fan. good luck :)
