Welcome to Automotive Forums. If the high speed works but nothing else it is the blower motor resistor. If none work it is the switch on the dash or a bad connection at the blower motor. The blower motor is under the dash on the right side (passenger). check the wire going from the resistor to the blower motor. Sometimes the electrical connecton to the motor gets hot and it will cause a bad connection. Also, it is in a positon where a passenger might hit it with a foot. I might add that it could be the blower motor itself.
