I just read your post again and you have A/C, so I don`t know if my car is the same since it`s heater only. I can tell you what my car is like. Your blower motor should have two connections but your switch should have three.The resistor is on the heater box with the coiled wires. These connectors (on the resistor) should be connected to the two green wires on your switch, they will regulate how much power the motor receives. the black wire on your switch should go to the motor. There`s a ground wire (brown)that should connect from the motor to a retainer clip at the heater core connections and then run over to the passenger side kick panel and connect to the car body beneath it. HTH.
