The blend door cable may have come off or a bad blend switch

.....I know it has been a year, but I am unsure where Firebird pulled his answer from. Turn AC off, disconnect battery, let it sit for 5 minutes. Reconnect battery, turn key into on position, with AC still off, let it for another 5 ( Should work in 2, but why risk a headache over 3 minutes). Turn car off, let sit 2 minutes, turn car on and check AC. You may simply needed to reset the actuators. If that does not work, check your fuse box. There are 3 fuses. If all are good you will need to move on to your blower motor resistor. Look up videos on youtube to test/replace it.I am reasonably sure it is simply a calibration issue
