sounds like the blower motor. its located under the glovebox. there are 4 8mm bolts holding it in along with the air duct hose and electrical connector. Its a good idea to also change the blower motor resistor. Heres a video https://www.youtube.com/watch?v=9f3iwcAeqi4
Edit: Check your fuses under the hood along with the ones on the driver side. fan replacement can be a pain.
