2000 park avenue climate control

I changed the engine and had the battery out for about 9 hours. Since then the AUTO on the climate control is illuminated but the blower does not work unless you push some other button on the climate control and then push the auto button. The climate control will work normally until the ignition is turned off and then the above procedure must be done for it to work in AUTO. Suggestions?

You can try looking at this thread, they mention with engine running, turning off AC, turn off engine, turn key to run position and recalibration should occur. It also mentions dealer having to reset system if battery is disconnected.
