    Test your fuses. Disconnect the radio and see whether the blower resumes operation. Test at the blower motor harness to see whether power is reaching the motor. Test resistance at the blower motor harness/resistor to ground; assuming the dash switch controls ground-routing to through the resistor assembly. Remove the motor and supply 12v directly to it. (watch those fingers!)

    your problem is the connectors on the switches and maybe the HVAC harness. This is a common noob mistake. Take the adapter out again and make sure that you plugged the vacuum switches into the switch on the right. Once you do that you can put the assembly back into the car. Be sure to plug the large white HVAC plug back onto the harness as well (this is the one which has all the connections leading to the switches).
