== == There are three electronic actuators under the dash: one is for the defroser, one is for the bank of four passenger vents and one ( this is you) sends air to the two driver side vents, the two mid-dash vents and the two rear vents. Either this actuator is faulty, or there's a problem with the electrical delivery system; mainly, the whole climate control panel in your dash (dealer cost: about $700.00).
