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?
