For about a week when I turn on the air conditioner I hear a rattling or something hitting fan blades. it is intermittent and air conditioner works fine. It comes from the passenger side air vent.

check for leaves or some other junk hitting blower cage you will need to remove blower for this. sometimes stuff works it way down from defroster ducts or leaves.
