odds are its the blower resistor. This controls blower speed by several resistors. the high speed bypasses the resistor. Its kind of a pain to replace as you almost need 3 hands to hold it in place and get tools and screws. It should be located at bottom of a/c case on pass. side. insed vehc. there will be several wires going to it.
