I'm going to say you have a vacuum leak. My 500 blows fine through the center vents but will go to defrost vent for no reason. I guess we have to get behind the dash and check the servos

hello believe or not try to charge the system most likely low. if it is low for some reason it operates that way. that is the first and cheapest thing to try. Ive seen it many times at the dealer.good luck
