Hi, my car did the same thing. It is the heat resistor fan speed control switch. t is usually found near the firewall on the passenger side. The part can be bought at most any auto parts place, cost about $35.Google your vehicle/heat resistor fan speed control switch and you should be taken to a page showing you where it is located. Good luck, Kathy
