Answers :

The KAM circuit for the PCM and the a/c is on the same circuit.
If the PCM does not have memory voltage it will loose the settings every time you turn the key off.
You might want to check the fuses in the engine compartment for a blown fuse for this circuit.
Of course it could have another problem too, such as a faulty idle air control valve.
