on my 03 h2 the heat and air have stopped coming through the dash vents and will only blow at the defrost vents up by the windshield. anything you guys know to check or maybe what the cause of this is? it just started this yesterday. any help would be greatly appreciated. thanks brian

 

If it is actually still blowing out the defrost vents, I would say it is an actuator problem. If it were not blowing at all, I would say it was the connector/resistor for the blower motor. I just had to have my connector/resistor replaced at the dealership.
