Can't figure this out. With blower on high, it will change the airflow to defrost, it will stay that way until I turn it off and then on again. Thinkin maybe its a vacuum leak somewhere???

yes, definately sounds like a vaccum hose leak. check the vaccum for any visual damage and the hoses. you may find a hose disconnected somewhere.
