It blows cooler on outer vents but only blows cooler air for a few seconds. Only the top two blower switches work on high and higher. Just went out its been extremely hot 100+ past two months. It used to vibrate real bad when in park and ac on now when in park and ac on it doesnt vibratr at all. And seems to have more power maybe. Help!
