Got it back last night and the technician says this is normal and gave me a copy of a page out of their manual and there should be 95% air coming out in the face mode, 60% in the face foot mode, 20% in the foot mode, 15% in the defrost foot mode and 7% in the defrost mode, and there should be airflow at the driver and passenger side demisters at all times. The owners manual does not say the same as the copy I got from him. I dont know why Nissan does this but my personal Ford and my work Chevy dont.
