Blower motor is under glove box area on passenger side. Remove the cover underneath that side of the dash, you'll see the motor.
Once you have finished the job, check the area beneath the windshield (outside). If there are plastic coverings missing replace them they are there to keep leaves and other debris from getting into the blower housing.
